For a number of years now, I have been a big fan of network attached storage (NAS) in order to keep all of my data in one place and simplify my photography workflow. Having access to the same fast storage from multiple machines, as well as the Internet, is important for my needs, so I have been utilizing NAS heavily at my home office. Ever since I got ahold of the Synology DS1815+, I have been a big fan of Synology products. However, there has been one main limitation that I have been struggling with when processing large files or accessing storage from multiple computers, and that is network throughput limitations. With the DS1815+ model only featuring 1 Gbit Ethernet ports, I have been limited to a maximum total of 100-120 MB/sec transfers, which is simply insufficient in today’s high-resolution photo and video environments. So as soon as Synology announced its DS1817+ unit with the capability to add a 10 Gbit network card, I knew I had to move up to it. In this review, I will provide detailed information on the Synology DS1817+ NAS and provide detailed information on what one can expect from it in terms of performance and network throughput.
Let’s go over the base specifications of the Synology DS1817+ first.
1) Synology DS1817+ Overview
Synology has a large array of different storage solutions that it offers to individuals and small businesses, as well as larger enterprises and the DS1817+ is a NAS device that is aimed specifically at small to medium size businesses. With its ability to accommodate up to eight 3.5″ drives and a very robust and scalable architecture that can handle up 96 TB of total storage (with 8x 12 TB drives and even more with expansion units) and up to 10 Gbit of network throughput with an add-on card, the DS1817+ is a powerful NAS that can address a lot of storage needs. Similar to its predecessor, it runs the same Quad Core 2.4 Ghz Intel Atom C2538 processor, which Synology chose for reduced power consumption and long-term efficiency, but its RAM can now be upgraded all the way to 16 GB (while the DS1815+ was limited to 6 GB total). Ability to expand RAM up to 16 GB is important, because one can run more apps in the background on the new unit. Speaking of apps, that’s the beauty of Synology NAS devices – we are not just talking about a pure storage device, but a pretty robust server that can host a number of web server applications for backup, file hosting, scripting and much more. You can host your own WordPress site and even use the Synology DS1817+ as your home iTunes server. In addition to these, the new DS1817+ has all 8 internal SATA ports at 3 Gbps, whereas the DS1815+ was limited to 1.5 Gbps on ports 7 and 8 (chipset limitation). This means that you can run the DS1817+ at full speed with all 8 drives, something you could not do on the previous generation NAS.
But the biggest and the most important change is the ability to add an extra PCIe card, something one could not do on the DS1815+. The extra slot can be used for either a dedicated 10GbE card, or an adapter that can take dual M.2 SSD drives for cache. This is a very important and welcome change, since it is now possible to take a full advantage of the combined speed of hard drives over 10 Gbit/sec – the DS1817+ is capable of pushing up to 1,179 MB/s read and 542 MB/s write speeds, which is just under the maximum throughput of 1,250 MB/sec of 10 Gbit network. See the next section on what I purchased for my network to get the best out of the unit.
Take a look at the back of the DS1817+:
As you can see, the right side of the unit has a slot for a PCIe card. In order to make room for this, Synology moved all interface ports such as Gigabit LAN, USB and eSATA to the bottom of the unit. This slightly changed the dimensions of the unit and made it a bit larger compared to its predecessor (166 x 343 x 243mm vs 157 x 340 x 233mm), but the difference is quite minimal and not very noticeable when the two are put side by side.
Just like all other popular NAS storage solutions, you can utilize pretty much any kind of RAID for storage: from Synology’s proprietary “Hybrid RAID” all the way to RAID 10. The device will also allow expanding your storage with additional or larger drives with Hybrid RAID and other RAID protocols like RAID 5 and 6, so it is a pretty flexible system.
The Synology OS supports many different types of file systems like EXT4, FAT, NTFS and HFS+ and many network protocols are available to provide the best security and compatibility between different operating systems. I have been using both DS1815+ and DS1817+ from both Windows and MacOS computers and I have also connected a number of other network devices to them to stream HD content through the network. And that’s the whole point of owning a Synology NAS device – you can put everything you have on the network and centralize your data for shared access between devices. In contrast, a direct-attached storage (DAS) device does not have such capabilities and would require a connected computer to be able to share its data with other devices – see the DAS vs NAS section of the Storage for Photography article for more details.
When it comes to interfaces, they are pretty similar to what was already there on the DS1815+. There are 4 total 1 Gbit RJ-45 LAN ports for network connectivity, which you can use if you are not planning to use 10 Gbit network and aggregate, if needed. There are a total of 4x USB 3.0 ports (3x on the back, 1x in the front) to connect other devices and external hard drives. And if you have storage devices that connect via eSATA, there are two of those ports available on the back as well. In addition to being able to connect external hard drives, you can also connect a wireless adapter to allow connecting to the device wirelessly.
Size-wise, the DS1817+ is fairly large, but pretty compact for an 8-bay unit. It weighs 6.0 kg without hard drives and has two large 120mm fans on the back of the unit for cooling and quieter operation. Additional notes on how quiet the unit is are provided further down in the review under the “Noise” section.
Just like its predecessor, the DS1817+ comes with a 3 year manufacturer-backed hardware warranty.

2) 10 Gbit Network Card Setup
The Synology DS1817+ does not come with a 10 Gbit setup ready to go, so you will need to get the right network card for it. Synology sells two network cards that are compatible with the DS1817+ (models E10G15-F1 and E10G17-F2), but those only give you SFP+ connectivity. Unless you want to mess with getting SFP adapters and fiber cables, I would not mess with that option and instead go straight with RJ45, which is simpler and cheaper to implement. Grab a dual port X540-T2 and you are all set on the Synology side. For your computer, get the cheaper single port X540-T1 or any other 10 Gbit RJ45 card that you can find, plus a CAT-6 crossover cable and you are good to go! This is the cheapest way to get 10 Gbit network without having to buy an expensive 10 Gbit switch. If you have another computer that needs 10 Gbit access, then use the other 10 Gbit port on the network card. What about access to the network and the Internet? Since the Synology DS1817+ comes with 4 extra Gigabit ports, you can connect any of those ports to your local network and your router, so that you can access the device from your LAN or the Internet. Now if you want to have a full 10 Gbit network with a proper switch, then take a look at my 10 Gbit for Photography Needs article, which covers everything you need to know about such a setup.
3) Hard Drive Installation
Installing hard drives is very easy. All you have to do is push the lower part of a drive bay, then pull out the drive tray. You would have to remove the fastening panels on the sides, then put the 3.5″ drive with its connections facing the other way, then finally attach the panels and use four screws to secure the drive. You can install all 8 drives in 5-10 minutes easily. The drive trays work with both 3.5″ and 2.5″ drives. If you have 2.5″ regular or SSD drives, you will have to mount those from the bottom of the tray. The last step is to insert the tray back into the unit – push it all the way in so that the power and data ports connect properly and securely. Obviously do all this while the device is powered off! If you want to prevent accidental removal of drives, you can use the provided tray key to lock each drive tray.
You can find all this information in the installation manual, with images to assist you in the process:
4) Hard Drive and RAID Recommendations
While you can certainly use any drive type and you can also mix and match any size drives, I would recommend to thoroughly plan your storage space in advance. If you are only starting up with a few drives, start out with larger capacity ones so that you can simply add similar drives in the future. If you utilize RAID (and you should), it is always best to use the same drives with the same capacity. For the DS1817+, I would start out with a minimum of 4 drives for a RAID 6 array. Although Synology’s Hybrid RAID sounds appealing, I would only consider it for an environment with different capacity drives. Since modern hard drives have a lot of capacity today (up to 12 TB), I would not recommend RAID 5 for a large capacity NAS or a DAS unit – go for RAID 6 or RAID 10 instead. RAID 6 is a bit slower than RAID 5, but the extra parity scheme will ensure that your data is still retained in case another drive fails during the rebuild process.
As for drive recommendations, there are lots of options out there and it really depends on your budget and your needs. For most people, I would recommend to go with drives specifically created for NAS environments, such as HGST’s 8 TB NAS drives. If you have a larger budget, the HGST 10 TB NAS drives are very nice and if you want to max out the capacity of each drive, Seagate’s 12 TB IronWolf drives are the way to go. Personally, I have always had good luck with HGST drives and I have yet to see one fail, so it is definitely the brand I would recommend for long term NAS use.
5) Getting Started
Synology really worked hard on making its graphical user interface (GUI) very easy to use and you do not need to have any advanced storage or programming skills to get it up and running. Once you connect the DS1817+ to your network and attach the power cable, simply press the power on button on the front of the device and it will start booting. You will hear a beep once it boots up. You can then fire up your browser and type “find.synology.com” or “diskstation:5000” in the URL and you should see a screen that says “Web Assistant”:
Just click the “Connect” button in the center and you can start the setup. If nothing shows up when you type the above in your web browser, my recommendation would be to download the “Synology Assistant” utility from Synology’s web site. As long as your network is operational and you have a running DNS server (which should be your router), it should work.
The installation process from there is very simple. First, install Synology DiskStation Manager (DSM), which is Synology’s operating system, which you will be guided to do during the setup process:
The system will warn you that all data will be wiped out from the hard drives that are installed, which is fine, considering that you have brand new drives mounted in the unit. It will take about 10 minutes to install and reboot the unit, with the latest version of DSM up and running. From there, it will ask you for things like server name, username and password, so make sure you specify those. You will then specify when to check and install the latest version of DSM as it becomes available – I chose to install the latest versions automatically very early on Tuesday and Saturday of the week:
As you can see, I also enabled SMART checks and bad sector warnings in case drives start to fail.
After that, you will be able to login to your new DSM install. Once in, go ahead and go to the Control Panel and head on to “Update & Restore” to update the operating system to the latest version. After the update process is complete, the system will reboot and you will hear another beep that indicates system readiness. From there, head on to configure the storage by clicking the icon on the top left side of the screen and selecting “Storage Manager”:
For my setup, I clicked on “Volume” and created a new RAID 6 volume that spans all 8 drives and picked “Btrfs” as the file system (recommended by Synology):
The process of building the RAID 6 array is quite long – the parity consistency check is going to run for a couple of days, depending on how big the drives are. Although you can access the volume while that is taking place, I would recommend to let it run and complete fully, just in case. This way, if any errors take place, you will be able to catch them early on.
6) Setting Up the NAS and Shared Folders
After you have the array going, the next step is to create a network share. Go to Control Panel, click “Shared Folder” and you will see a list of current shared folders. I went ahead and created two separate folders: “Storage” for my main storage where I put all work-related files, photos, videos, etc.:
The nice thing about Shared Folders, is that you can create as many of those as you would like and they keep files and folder separate, while sharing the total disk space. You don’t have to worry about things like partitioning your volume into sub-volumes.
The next step is to create users and assign permission to shared folders. Simply click the “User” icon in Control Panel and create your users. I created a couple of users for me to use on the network:
Then went back to the created Shared Folders and modified the permissions for those users to allow Read and Write operations.
Another area to check is “File Services”. If you want to access the network share from different operating systems, you need to make sure that particular services such as SMB, AFP and NFS are enabled (depending on what you are planning to use):
The next step was to visit the “Network” icon and set things like Server Name and IP address, so that I could easily access the device on my network and not worry about changes when I reboot the device or my router.
That’s really it!
7) PC and Mac Access
All you have to do from there is type “\\Server Name” in “My Computer” within Windows OS and you will see a list of shared volumes:
If you have a Mac, you should see the Synology DS1817+ device under “Shared” within your Finder. For easier access, you can drag and drop the shortcut to your Desktop.
8) Connecting External Devices
The Synology DSM OS will automatically recognize practically any connected storage and automatically share the device. Once you change permissions, you will be able to access the connected device just like you can connect to the other network shares, as seen below.
Next, make sure that you set the appropriate permissions under “User” to the connected device. You are done, now you can access everything in that external drive:
This is particularly useful for backup purposes. Don’t forget that your Synology device should NEVER be the only source of your files. You should always keep a backup of everything, particularly your critical files somewhere else. So my recommendation would be to get separate external drives that you could use for local and off-site backups. You can manually copy files, or you can use Synology’s “Backup & Replication” tool, or the “Cloud Station” app to backup your files from the device to external drives or to the cloud.
Performance-wise, the Synology DS1817+ is pretty incredible when accessed via 10 Gbit network. I have already pointed out that it can do as much as 1,179 MB/s read and 542 MB/s write speeds, but those are the numbers provided by Synology in their own lab. I wanted to see how far I could get with the 7200 RPM performance NAS drives I hooked up to my DS1817+. I performed two different kinds of tests – one was to see how fast RAW image file transfers would be when compared to the older DS1815+ unit, then the second test was to do pure performance benchmarks using CrystalDiskMark and compare the results with the QNAP TVS-882T that I have been using simultaneously in my 10 Gbit network environment.
Here is what the result looks like when copying a total of 688 images. First, with the Synology DS1815+ that is limited to 1 Gbit/sec throughput:
As expected, the bottleneck on the DS1815+ is its gigabit interface that slowed things down drastically. On average, I got about 104 MB/sec speeds and it took 2 minutes and 20 seconds to copy the files. Next, I tested the DS1817+ over the 10 Gbit interface:
That’s a whole lot better at 427 MB/sec – it only took 34 seconds to complete the whole operation, which is pretty impressive. Those are the kinds of speed improvements you can expect from a fast NAS device!
The same thing can be expected when performing tests over CrystalDiskMark:
It is very clear that the Synology DS1817+ is the way to go for any environment where storage performance is important. As you can see, one can get over 10x read performance and close to 5x write performance when using the DS1817+ over the DS1815+. Sequential read and write performance is also impressive – over 6x read and over 4x write performance advantage.
10) Synology DS1817+ vs QNAP TVS-882T
When it comes to comparing the Synology DS1817+ to the QNAP TVS-882T, the latter has a lot more features in comparison, thanks to its PC-like architecture. The QNAP is a robust storage solution with built-in storage tiering, something that is rarely ever found on non-enterprise devices. It has the ability to host up to 2x M.2 drives (SATA only, no NVMe) right on the motherboard, while if you go with M.2 drives on the Synology DS1817+, you will need to use the single available PCIe slot, compromising the 10 Gbit connectivity option. The QNAP TVS-882T can be expandable up to 64 GB of DDR4 RAM, thanks to its 4x RAM slots, whereas the Synology DS1817+ is limited to 16 GB. Lastly, the QNAP can be directly connected to a monitor or a TV for output (3x HDMI ports) and can be used as both NAS and DAS (2x Thunderbolt 2 ports), whereas the DS1817+ lacks such connectivity options – it is simply a NAS storage device and it is only designed for this one task.
At the same time, the two storage units are designed completely differently in terms of architecture. Since the QNAP TVS-882T is basically a powerful PC with a full-size CPU, it eats up quite a bit of power, whereas the Synology DS1817+ is extremely power efficient, consuming as little as 32 Watts when hard drives are in hibernation mode and only double that at full speed. There is also a big difference in pricing between the two – the Synology DS1817+ costs only at $850 for the 2 GB RAM version and $950 for the 8 GB RAM version (plus the cost of 10 GbE network card), whereas the QNAP TVS-882T goes for $2,500 (10 GbE included). Therefore, for someone who wants an affordable storage solution, the DS1817+ is relatively inexpensive both in terms of upfront and future energy costs.
What about performance differences between the two? Let’s take a look:
As you can see, the Synology DS1817+ is able to match the sequential read speed of the QNAP TVS-882T and it is not all that far off in sequential writes either, which is pretty impressive for a low-powered NAS device. However, when it comes to random reads and writes, the story is a bit different and that’s where things like storage tiering with faster SSD drives can make a difference for the QNAP. As shown in the above chart, the QNAP was able to achieve 2.5x faster read and 2.4x faster write performance, which is certainly a significant difference. So depending on your workload and requirements, you might want to evaluate both and see which one is the preferred solution.
Although the DS1817+ is designed to be a very quiet NAS, once you load it up with fast 7200 RPM NAS drives, it will surely add quite a bit more noise to the unit. I would recommend against putting the DS1817+ on your desk, because micro-vibrations might create extra unwelcomed noise. Putting it on the floor with straight and firm surface would be a better choice, but ideally, it is best to keep it in a separate server or storage room to make it less irritating. That’s the general problem with all NAS and DAS units though, as they can add a bit too much noise to the environment. Just make sure that you are providing adequate cooling and monitoring the device through the network, so that you get alerted if one of the drives fails. Noise levels on the DS1817+ are a bit better than on the QNAP TVS-882T, thanks to its larger and quieter fans. When QNAP gets hot and its fans speed up, it gets noisier in comparison, since it has a total of 3 smaller fans (2x 80mm and 1x 90mm for the CPU). Synology measured the noise levels at 22.2 dB with the device loaded with 8x 1 TB Western Digital 5400 RPM drives. So expect the unit to be a bit louder with 7200 RPM NAS drives.
12) Sharing Lightroom Photos
Since getting a hold of the DS1817+, I have completely migrated all of my photos to the unit and have it actively back-up all the data to another smaller NAS – I no longer store any photos on my computer. Here is my current workflow:
- The “Photos” folder, along with each year subfolders are located on the DS1817+:
- All Catalog files (without subfolders) are backed up in a “Lightroom” folder on the DS1817+:
I create catalogs for each year, as explained in my “How to organize photos in Lightroom” article.
- I store all Lightroom catalogs on each device separately, in the fastest drive available (usually SSD or M.2 NVMe Flash drive).
- When accessing photographs from catalogs, all files are mapped to the DS1817+, as seen below:
- The above process works the same for every device that needs to access photos. The only thing I need to do is copy Lightroom catalogs locally to each computer and keep them up-to-date, since Lightroom does not allow opening catalogs from network shares and it does not support multi-user access.
Since all photographs reside on the NAS, I no longer have to worry about backups either, as explained below.
13) Automated Backups to Another Synology Array
In addition to the Synology DS1817+, I own the fire-proof and water-proof ioSafe 214, which I now utilize purely for backup purposes. If you own a Synology or an ioSafe device that relies on Synology DSM, you can use the free Cloud Station app on both devices to keep all of your critical files in sync. This app works beautifully, because all changes to your primary storage will automatically replicate everything into the backup storage over the network. And if you keep your secondary backup storage in a different physical location (which is a great idea), you can configure the two devices to sync over the Internet. Since the app would be native to both units, unless your network goes down, you do not have to worry about synchronization issues.
Looking at both the Cloud Station app on my DS1817+ and the Cloud Station Client, I can see that all the files are being synchronized without any issues and the latest data is available on both. It is good to know when your data is safe in case anything happens! And if you work in a workgroup environment and want to recover changed files, there is even built-in version control, which is very nice.
Having been using the Synology DS1817+ for the past 6 months, I have to say that I am very pleased with its overall performance. While the previous generation DS1815+ served me well for several years, its biggest limitation was its network throughput – with only 1 Gbit network ports, there was only so much I could do over the network, which forced me to only use it for backup and secondary storage purposes. With the DS1817+ upgrade and the new ability to run 10 Gbit network, I was able to fully take advantage of the NAS, which enabled me to transfer files at incredibly fast speeds that even surpass my local SSD drives in terms of read and write performance. Because of this, I ended up migrating all of my images to the NAS and use photo editing tools like Lightroom and Photoshop to open files directly from the network share. With the DS1817+, I was able to simply my workflow even more and take advantage of automatic backups that replicate my data across several other storage devices.
With its sub-$1K price-tag, the Synology DS1817+ delivers a lot of value for the money, so it is an excellent network attached storage and backup choice for both photographers and videographers alike. With hard drives increasing in capacity and costs decreasing year by year, purchasing a solid device like the DS1817+ will cost less than buying a high-end professional camera like the Nikon D850. With the setup I proposed above, you can get a fully loaded system that gives you up to 48 TB of usable space at $2,000 for 8x 8 TB drives and $850 for the DS1817+, totaling roughly $2,850. And if you want to get started with less drives, you can decrease that cost even further. The point of NAS devices like the DS1817+ is to consolidate all of your data in one place, which it does beautifully. I can access all of my data from every device at home and even from remote locations, which is amazing. Synology’s DSM is the easiest operating system I have used to date and it gives so many options to expand the functionality of the device directly from the GUI without messing with any command prompts. If you are a working professional or an enthusiast with high storage needs and you are looking for a storage solution you can depend on, you should take a serious look at the Synology DS1817+.
Lastly, if you find 8 bays to be too much for your needs today, Synology offers smaller solutions as well, like the 5-bay DS1517+, which is also an excellent choice for photography and videography needs, sporting very similar features as its bigger brother.

Photography Life Overall Rating
Hi, great article. I’ve had a DS1817+ for a while now. It backs up to a DS1813+ which is still going strong. All my RAW files are on the DS1817+ and I have my LR catalogs on a local NVMe drive. I don’t run 10G (yet!) but I wondered do you recommend using Jumbo frames in your network setup?
A curious comparison between the 1817 and the 1817+ is that the lower spec 1817 has 2x built in 10GBe and 2x 1Gbit connectors (the 1817+ has 4x 1Gbit), has a lower spec CPU that draws more power the 1817+, is 32 bit instead of 64 bit, and trades off not being able to use BTFS. Why they put the 10Gbe into the lower spec model and not the 1817+ baffles me.
Thanks for the great article.
With regard to the 427 MB/sec write test you performed/mentioned above. Was that on a drive configured for RAID6? I wanted to be sure that I will get those speeds out of RAID6 1817+ before I upgrade to 10GB ethernet.
Bought the X540-T1 for my PC as you suggested and for some reason can’t get it to show up on my computer even with drivers installed. Any idea why?
I am looking seriously at this NAS – its time. Do you have an opinion on the value of using Enterprise class drives? Is the value only in the the additional 2 year warranty or are they more likely to last even longer? Or am I kidding myself and just spending more $$?
Cal, it depends on how much you are going to be using this NAS. If you are going to do a lot of reads and writers constantly, then I would get enterprise-class NAS drives. If you are going to use this device for storing your photos / video and working on them, then go for regular NAS drives. Personally, I have been using regular NAS drives from HGST for a number of years now and I love them.
Isn’t that a typo: “96 GB of total storage “, it should be 96 TB I suspect.
Thanks for catching the typo – you are right, it is supposed to be 96 TB :) I fixed it in the article.
I think, but don’t quote me on it, that your read / write speeds are also impacted by which Raid Array type you choose to utilize.
( They vary from blistering speed ( Raid 0 aka Striping ) to ultra-protection ( Raid 10 aka Mirroring and Striping ) and everything in between )
I have a Synology, but is a little brother to this one as it only has four drive slots. I don’t take nearly as many photos as you all do, so I just
dump the days images onto a TB SSD, do the sort / cull thing and move the ones I plan on keeping to the NAS thereafter.
IMO, and it is only that, if I were going to spend the money on the unit, the drives to feed it and all the 10G networking hardware, ( a decent amount of money in reality ) I might just go with the Fiber / SFP setup as the next logical step will likely be 40GB interfaces and those will certainly require a fiber connection. Might also consider it if you’re running your Cat-6 anywhere near power cables, light fixtures, etc. due to noise / interference.
Additionally, with the Synology units, you can choose to encrypt entire folders and put anything you want in them. You can tell the unit to mount them automatically ( not recommended as it defeats the purpose of encrypting it ) or manually mount them with the encryption key when you need to access the contents. Once mounted, they can be accessed like any other folder from the network.
Also, these units actively get out on the internet periodically to look for updates so if this is behavior you would rather not see, make sure to block the unit at your router. I prefer to let others beta-test updates and ensure my unit has local access only until I say otherwise.
Finally, if you’re network savvy, if you setup a VPN server at home ( Open VPN works well ) you can still access / transfer your photos on your NAS unit from pretty much anywhere.
Great review. Two questions:
1. In what scenario’s are the 4k read/write speeds important? This seems to be the critical difference between the Qnap and Synology, but I don’t know if it’s relevant to my workflow?
2. I’ve read that this unit has severely restricted airflow around the drop-in 10b gb card and that this could cause heat build up and data error issues. The 1817 (non plus version) of this unit has 10 gb built in and it is just as (and in some cases) faster than the 1817+ and cheaper. I’m not sure why I wouldn’t just buy the 1817. The only thing holding me back on this is that the 1817+ has BTFRS file system. Wondering what your thoughts are on this. I only need this unit to connect to my main machine and possibly may want to access databases from my laptops in my house, but that is it. Nothing over the internet, so I don’t need all of the apps, power and functionality of full NAS.
Chris, 4K read/write is random read and writes using small file chunks, whereas the “Seq” stands for sequential writes when you are reading or writing a very large single file. If you have a ton of small files that need to be accessed, 4K Q32T1 stats are important. For large files, sequential read/write are important. For photography needs, we mostly deal with larger sequential files (large RAW or large TIFF files), so sequential in my opinion is a bit more important. Lightroom uses a lot of smaller files (thumbnails, previews, etc), so for its operation the 4K stats are important. However, those are not the files that you will be storing on your NAS storage anyway – Lightroom always requires those files to be on the local storage, which is why you store your Lightroom catalogs in a very fast SSD or Flash drive.
As for airflow issues, I haven’t noticed any serious problems with my unit and I have been running it for the past 6 months. If you know that the space you will be putting it in is hot and is prone to get hot, then that could be something you should take into account. My unit sits in the basement in a cooler place, so I haven’t noticed any issues. As for the new DS1817 non-plus version, indeed, it does have 2 10Gbit ports, so it might be the way to go instead of the DS1817+. Keep in mind that the DS1817 was released later than the plus version and I already had the DS1817+, so I could not test both to see which has better airflow. However, based on BTU ratings, the non-plus version is supposed to be hotter and noisier in comparison. Also, don’t forget that the DS1817 has weaker specs than the + model. It has a slower CPU, less maximum RAM (8 GB vs 16 GB), less number of ports (mostly not relevant, so not a big deal), and no support for BTRFS, as you have already noted.
I think for your needs, it might make sense to go for the cheaper DS1817, since you don’t need many apps and BTRFS alone isn’t worth going for the plus model (EXT4 is fine too), in addition to spending extra cash on a 10 Gbit card… Just my 2 cents.
Hope this helps!
Thank you, Nasim.
Interesting that you mention the catalogs vs. the images. I currently keep images on external Raid but catalogs on an additional internal SSD. I have maxed out the internal 480 GB SSD with catalogs data however, without any smart previews or 1:1 previews. My intention with external 10 GB was to move catalogs to external. Knowing that it appears that the 1817+ may be a better option.
The issue of the ventilation came from a Storage Review article: www.storagereview.com/synol…nas_review
That said, the DS1817+ is somewhat of a mixed bag overall–something you don’t hear very often when we review a Synology product; performance lacked in several areas where it should have excelled, which certainly due to the design flaw where the add-on card slot is poorly ventilated, thus leading to overheating and sluggish performance. Because the PCIe slot is a huge selling point for the newer Synology NAS solutions, this makes for a significant issue.
This concerned me greatly as overheating and performance issues also typically means data errors that are often not detected easily, especially when dealing with Terabytes of information.
Anyway, it’s a difficult decision. Cost aside. 1817 (slightly more noise, better performance in some areas, worse in others, seems to have less chance of design flaw that would cause heat or data issues, but older EXT4 File system). 1817+ (less noise, mixed bag on performance, potential design flaw, improved file system – BTFRS – ).
Chris, I think the concern with the PCIe slot would definitely be an issue if one were to run M.2 cards, which get very hot. If there is no ventilation, it would certainly affect the performance in a negative way. However, it is not a problem for network cards, which do not get very hot in the first place, which is what I am running. If you need to run M.2, I would not recommend the DS1817+, as you would be better off with something like a QNAP unit instead…
Great. Thank you, Nasim!
excellent review – thanks a lot!!!
You are most welcome Robert!
Thank you writing this article. It is way above my understanding. I will describe what I want and then if you can tell me if this is the type of thing I need. From early next year it looks like I will be doing short term contracts with a bit of travel between for 18 months-2 years. I have a great work horse travel laptop it has 135 GB of storage which is reasonably light and fits inside my cabin luggage. I do a lot of time-lapse photography that involves up to 1000 Raw files from my EOS 6d. It handles these a bit slowly. What I want is an off laptop storage that I can use like it is an internal memory.
Mark, it is probably best for you to go for something like this instead. Just make sure that your USB port is USB 3.1 to take advantage of the storage speed.
The above NAS solution is for a home-based setup where you have a ton of files that you need to store and access.
