I started using NAS servers just under a decade ago, and at the time, I was looking for a centralized location to manage my media collection. Up until that point, I had mechanical hard drives in my gaming machine, but when I switched to SSDs, I decided to get a storage server instead — it just made more sense to have a dedicated machine handle media storage and streaming.
In Hardwired, AC Senior Editor Harish Jonnalagadda delves into all things hardware, including phones, storage servers, and routers.
I dabbled with FreeNAS (now called TrueNAS) in the beginning, converting an old machine with six HDD bays into a home server. While it did the job admirably, I wanted something smaller, so I got the DiskStation DS414+ to see how a pre-built NAS enclosure would hold up. It wasn't as powerful as my custom build, but it took up much less room, and it had all the features I was looking for.
I used the DS414+ for nearly four years, switching over to the DS1019+ as soon as it was introduced back in 2019. The DS1019+ had much better hardware, polished software with plenty of utilities, and five drive bays in total. I still use the NAS to back up photos and videos from the dozens of phones I test every year.
The DS1019+ handled Plex duties as well, but I switched over to the DS1522+ for media streaming back in 2022. I used to back up data from these two enclosures to a Google Drive, but my storage needs went up considerably in the last two years, and it wasn't feasible to put over 100TB of data in a cloud provider. So when I got the beastly DiskStation DS3622xs+, I set it up to back up the data from the DS1019+ and DS1522+.
The DiskStation DS1823xs+ is a true powerhouse
While the DS1019+ is still going strong, the drives in the enclosure have crossed 35,000 hours, so at the start of 2024, I started migrating to the DiskStation DS1823xs+. Instead of using two servers, I'm setting up the DS1823xs+ as the ultimate home NAS that can handle both media streaming and backing up data, and my main consideration for going with this model is that it has more powerful AMD hardware — a Ryzen V1780B — along with 10 Gigabit Ethernet connectivity, and eight drive bays.
Synology doesn't usually provide 10GbE ports in its NAS servers, but the DS1823xs+ comes with one as standard alongside dual Gigabit Ethernet ports. The NAS is perfect for what I need in a home server, and while it doesn't have the ability to transcode Plex content, that isn't a feature I need.
I'm always running out of storage, so with the DS1823xs+, I wanted to go overboard. So I'm using four 18TB HAT5310-18T drives, a Seagate Exos X20, and an IronWolf Pro 22TB. The total addressable storage comes out to 114TB, and that should last several years. I still have two drive bays that aren't in use, and I plan to slot in dual 24TB IronWolf Pro drives over the coming months.
The DS1823xs+ comes with 8GB of RAM out of the box, and as it has two SO-DIMM slots, I added a 16GB memory module, bringing the total to 24GB. It also has NVMe bays, so I slotted in two 400GB Synology SSDs (SNV3510-400G) the brand sent over a while ago. The SSDs can be configured for storage, and the only reason I even went this route is for Roon; the audio service mandates installation on an SSD.
Putting it all together
It took a week to migrate the data from the other servers to the DS1823xs+, and what's immediately evident is just how powerful the NAS is against the traditional Plus models in Synology's portfolio. The DS1823xs+ is aimed at businesses, and there's a lot of headroom for the future. It is overkill just for storing media and backing up data from phones and Windows machines, and it does a great job running virtual machines as well.
The main issue with the server has to do to Synology's stubbornness with NAS HDDs. Essentially, only hard drives made by Synology are compatible with the NAS, so when I slotted the Exos and IronWolf drives, I got an error message that there was an issue with the drives (there wasn't). Thankfully, it is easy enough to make the error message go away, but it's an irksome limitation.
At the end of the day, the power on offer combined with the versatility of the DS1823xs+ means I don't need to switch to another NAS for a while. Of course, going this route isn't affordable in the least — the NAS itself costs $1,799 without the drives, the 18TB drives are $649 each, the Exos 20TB is going for as low as $309 these days, and the 22TB IronWolf Pro is now going for $439. Throw in a 16GB RAM that is currently $349, and the 400GB SSD is $149. That comes out to a total of $5,690 for the build, and that's frankly ridiculous.
I went with the DS1823xs+ as I already had the NAS, but if you're aiming to build a home NAS server, it is overkill. The DiskStation DS1522+ is a terrific choice, and you can fill it up with Exos drives as needed. While you'll get better hardware with other brands, I always turn to Synology's servers as they have the best software features. DiskStation Manager has the most refined interface of any NAS, and you get useful mobile utilities that let you access your data anywhere. Ultimately, this is the biggest differentiator for the brand.

Weird flex, but OK.Reply
So you bought a 6 bay underpowered overpriced NAS that complains if you dont use their proprietary hardware and loaded it with 6x20TB HDDs and call it ultimate? CLICK BAIT nonsense.....Reply
I hope you have backups of your backups and also a backup of your media if it's important to you. If you do a quick search on the Veeam backup forums, you'll find plenty of users who get file integrity errors when saving large Veeam backups to Synology NAS devices. Nothing to do with the backup software or source and everything to do with the backup target.Reply
In a corporate environment, we've used Synologys in the past for remote offices. They have chewed through disks like nothing I've seen before. SMART errors on multiple disks that appear at the same time, and after removing the disk and running a dedicated SMART scan they come back clean. A Synology running a lab environment lost it's array completely with healthy disks, and all Synology support could say was "hmm.. that shouldn't happen."
The thing is, most people use these devices for media consumption... what is a few bad bits in a 4K video? Maybe some distortion or skipped frames, and only in the unluckiest of cases would the file be unplayable. Bad rip? Bad download? Unless you have a checksum for the file, you'll never know if it's your Synology randomly corrupting data.
At the $6k price point you can buy a white label SuperMicro server with a JBOD controller loaded with disks running TrueNAS with no overpriced relabeled hard drives or other "supported" components to worry about. 100TB+ on a Synology is just a disaster waiting to happen...
I know a lot of people that use Synology and are happy with them. I understand some people just want something simple, compact, and relatively low energy to store lots of data. It sounds like your use-case, and this is perfect for that use-case.Reply
My previous NAS was almost as compact (U-NAS 810a case), also 8 bay, had dual 10gbit NICs, onboard LSI3008 for the 8 disks, a SAS3 16i HBA to connect external JBODs, 64gb of ECC RAM, a server-grade motherboard with IPMI, and a Xeon with iGPU (sufficient for transcoding 4k remuxes), and despite buying it ~5-6 years ago -- still came out cheaper than the Synology listed. I literally just finished a new 'NAS' (more server) and for the same cost as the Synology in the article, I got a 64-core EPYC, 512gb RAM, and another server-grade motherboard.
$650 for a single 'Synology' hard-drive is insane. It sounds like they give you the option to use other hard-drives, but to put things in perspective I typically buy 16tb for $160 and 18tb for $180. They are manufacturer-recertified drives, but I've had 0 failures out of >24 recerts over the past year, and depending on vendor the warranty ranges from 2-5 years.
I use TrueNAS, but typically recommend Unraid to others since it's a bit more flexible with expansion. I was surprised that your first NAS was FreeNAS, then you moved to Synology, since if you had the slightly-higher level of skill and effort required for FreeNAS -- you could have handled it a second time.
I think most people would have been more interested in an article about how to build a low-cost Unraid or similar NAS.
I manage a Synology NAS for a small non-profit that I support. Nowhere near as much storage that the OP is using. The subject says "Home NAS", but it sounds like a home business application. So, yeah, have a backup and restore solution for a NAS in that context, beyond whatever recovery is built into the installation RAID (or whatever); especially with the any issues being experienced, like the OP.Reply
Meh. I built my first "real" NAS out of a Power Edge 2950, 2 Norco SAS expander 24 bay enclosures, and 48 Seagate 4TB drives back in 2014/2015 w/FreeNAS 9.04.Reply
Since...I have updated to a fully "pimped" 3990X running 2 fully populated MD3060E enclosures (10TB, 12TB, and 14TB WD drives) right around the .7PB area. Running TrueNAS Core. Backup duties handled via a jail running P5 Backup to a Scalar i3 w/2 LTO8 mechs and 1 LTO 6. I have 2 SuperLoader 3 LTO6 units but don't use them to reduce licensing costs from Archiware.
Large capacity NAS units, even DIY aren't magic/special. Anyone w/rudimentary knowledge and some funding can throw hardware and cash at it and end up with something workable. The devil is in the details of the "care and feeding" wrt config, data safety and curation.
My use-case is I enjoy owning my own movie collection. After such a thing gets to a certain size threshold it becomes quite unwieldy. Where was movie/TV show X in the boxes/shelf/stacks again? Do we have movie/TV show Y, what all is available? Did children screw up a particular disc the last time they used it? Did they even put it back? After running into some/all of these, and/or streaming service license losses in the middle of a series binge, my goal was to get to a point where all of my media was accessible to me from any device anywhere. This involves full quality .iso and .mkv's of/from those .iso images. The curation/post processing involved represents a substantial amount of time/effort. Losing that would be a mighty blow; hence the backup solution/expense.
So again..."care and feeding" is the specialness. Your backup solution, as others have pointed out, is not ideal. I also have a DS1821+ that gets backed up of its data exposed via NFS mount to the Threadripper NAS.
