- Synology DS1821+ NAS Review nascompares.co...
Even to the most casual follower of network-attached storage, 2020 has been a fantastically truncated year of new hardware releases. Perhaps it is because the supply chain has been so fragmented worldwide, with people adjusting to new working practices, or perhaps it is simply the brand readjusting their release strategies in line with how companies have adapted to this new way of working. Regardless of what it is, we have seen the usually predictable pattern of hardware releases from brands like Synology be utterly thrown out the window. Into this wonderfully eclectic range of releases, we find the brand new 8-bay NAS solution for small and medium business hit the market, the DS1821+ Diskstation solution. This desktop NAS is geared towards prosumers looking to take advantage of the Synology Diskstation Manager (DSM) software, as well as working from a more flexible and adaptive hardware platform. Finding a place in the storage portfolio between the DS1621+ and DS1621xs+, this system arrives with all of the hardware benefits of the former but allows the user to save money and add flexibility over the latter. Arriving 2 years after its predecessor, the DS1819+, this system arrives with a newer CPU, better memory options, dedicated caching and scalability of its expandability in a number of key ways. But with other network hardware improving drastically in those 2 years and the demands from even mid-range businesses growing considerably, is this new Synology NAS a big enough jump to warrant your money? Does the Synology DS1821+ deserve your data? Let's find out.

One point of correction for those of you considering this NAS: according to Synology's specs on the 1821+, it appears the PCIe slot is x8 physical, but x4 electrical. You will not get ~8000 MB/s as noted in the video.
Thank you for highlighting this. I will look into this and adjust where appropriate
Pro Tip: If you have noise issues due to drive vibration, you can damped the contact point for the problematic drive with a small piece of adhesive backed velcro (soft side).
Really happy they are seeing AMD as a choice. Sadly when I needed to upgrade my ds213air. I ended up going for FreeNAS. But I do miss lots of things my Synology did.
In Korea, there was no video detailing this product. great help in choosing a NAS. Thank you!
Glad I could help you dude
I have the 1817+ and love it! Wish it supported plex hardware acceration.
As usual thanks for the FANTASTIC video. ALL of the Fantastic Videos. And I know in many you have addressed the Seagate 18TB IronWolf Pro Synology Compatibility alerts. I know you say “all is fine… it’s just an alert you cam ignore.” But I am still super scared. I just now put a 18TB drive in my DS1821+ with 4 8TB drives. And I got the SHOCKINGLY RED ALERT saying “Important data may be lost if you choose to proceed.”
I panicked and removed the drive. I had been sitting on the unboxed drive for 6 months WAITING for Synology to add it to compatibility. But it APPEARS it NEVER will. And it also appears that they may NEVER add any NEW drives to compatibility other than their own much, Much, MUCH more expensive drives. Problem is I have THREE eight bay Synology Servers and MANY clients with 8 bay Plus model Synology Servers. And now I am afraid to even REPLACE drives. The NEW 16 TB IronWolf Replacement [ ST16000NTZ01 ] ALSO gives these scary alerts.
I know I can’t deploy Synology Servers or replace drives if they will PERPETUALLY alert of “Important data may be lost”. A client would consider this a fireable offense. Have NO confidence in me as their consultant or Synology as a solution to protect their data. I own and have tried QNAP, but HATE the interface… But I MAY have to switch to them for clients [and personally] to avoid these SUPER SCARY alerts.
Have you heard if Synology is aware they may be SCARING customers AWAY from having confidence in their equipment. And/or making them much, MUCH more expensive that QNAPS if you HAVE to put in ONLY Synology Drives.
Have you heard if Synology will AT LEAST stop giving the INCOMPATIBILITY alert AFTER they have been installed and after that one SUPER Scary alert?
Most of what I do as a Mac Consultant is Synology Server support. But I’m totally terrified of this alerts on my own Synology Servers and my clients servers too.
What are you thoughts? And are you FULLY CONFIDENT that these alerts can be 100% ignored?
And, as a sidebar, is it true and Synology and Seagate have officially dropped support for IronWolf Health Management on all new drives… just 3 years after promoting the heck out of that?
What are your words of wisdom? And also what are your words of CONFIDENCE… That you can SUPER SAFELY proceed past all those BRIGHT RED alerts about LOSING DATA if you proceed.
And, with those alerts, I would imagine Synology would use that as an excuse to NOT support your troubleshooting if and when you have issues.
Please help with words of wonderful re-assurance of Synology having a present and Future with SEAGATE IRONWOLF Pro 18, 20 and 22 TB drives.
Thanks

Why doesn’t he ever reply!!! So frustrating. Try asking Will at spaceRex awesome guy!
Robbie, am I detecting a little gray young fella ?
Good review. Thanks as always.
This is amazing information. Thank you. Was thinking to pick this model up but wondering if you have an opinion on what nas would work for a video and photography person? I work with big big files on a weekly bases. Would love to edit 4K video straight from the nas but guessing might be too slow. Back up and safe storage is most important. Was planing this 8 bay with 20tb drives for 120tb total.
Also would be great to send links to video files to editors around the world. Would be a bonus.
Asking a lot I guess 😊 main thing is lots of storage.
This is exactly what I used it for, but as I always edit with proxies, the disk speed isn't an editing bottleneck.
thanks a lot for sharing your knowledge. Recently I acquired this NAS, now i want to upgrade the RAM to the Maximun that this device allows, the only problem is that the Synology ram is very expensive, I looked for some alternatives in Amazon and unfortunally i didn't find any alternatives, could you give some suggestions for this upgrade?
Super helpful comprehensive review.
Hi… if this device does not have embedded graphics and the 1621 doesn’t have it either, which device is the best for me to get for video editing as well as using it as a Plex server? I want to EDIT 4K video, and also have PLEX playback 1080 and 4K video as well. Is an embedded GPU necessary? What’s the alternative?
The only thing I really care about is this: Will this be powerful enough to Plex direct play a 4K blu-ray rip (bit for bit identical as disc, no handbrake) to my NVidia Shield?
Nooooo. Invest in a small server man. Why does everyone want this storage platform to be a massive plex beast? That is NOT what it is for.
Does anyone know if the Synology 25Gb Ethernet Adapter with 2 SFP28 Ports (E25G21-F2) will connect directly to a SFP28 card on a PC via SPF28 cord? Any idea of speeds (on the 1821+) with 8 drives with MVME Cache? I'm looking into purchasing both cards and cable and was wondering if it would work without a switch? Thanks!
Enjoy your videos. Will be buying a NAS soon. I have a question. My router is downstairs and my office is upstairs where I plan on keeping the NAS. Connecting to the internet? A wifi extender in my office to plug in to?
Nice!! Any advice on the NVME to use? As it is just for cache, i can only assume it doesnt have to be that big? 128/258GB should be enough? one only, of better 2? And also very curious on how to upgrade the memory without having to buy overpriced synology memory.
I bought 512 GB only for read cache. SAMSUNG EVO 970
!DS1823+ or Bust!
Synology does not list any 18TB drives on the compatibility page is that really true? With 8x18TB and 2 parity drives you end up with a module size of a bit less than 108 (I know you lose a bit more for the parity to work) which just happens to coincide with the maximum volume size.
Also.... Synology RAM is about five times the price of other compatible RAM from the likes of Kingston or Crucial. I know you can't recommend it.
I got a couple of questions, what the largest drive size, if I populate it with three drives (minimum for Raid 5) can I add more drive later? Can I add any Size drives? Can I remove drives later and add larger drives?
hey thx for the video i have two questions:
1. can i also insert m.2 sata drives instead of nvme drives?
2. can i use e.g. wd white label drives that only have two screwholes on the side of the hard discs?
please do you know what is the maximum M.2 NVMe SSD capacity the Synology DS1821+ can handle?
Two Questions: 1) can I connect multiple disk stations to run as one? 2) can I run toshiba enterprise HDDs (non-NAS) safely?
just ordered quiet fans for mine and 64gb non-ecc :/
Hello, great video, well I am new with this NAS thing, I want to buy the same model, DS1821+, and I want to populate it with 8 14tb drives... but I have a question... Is it also necessary to populate it with the SSDs NVME??... Thanks.
In my opinion no since they are only useful in some work loads
Ds1621xs over this with a 10gb card? Is there any benefit with ds1621xs+ expect if you run many vm machines. I
OK, You sold me, but I cannot find any in the UK at all? You mention a supplier but you are too quick and I cannot make out who they are, please provide a link.
iam on my way to buy the 1821+ but i dont like that this nas doesnt support any 3rd party nvmes? does anyone have 980pros or sn770 for caching in this nas? idlike read and write cache with dual 2tb sn770. idlike download from external ssd 400-500 gb every suturday-sunday night after weddings, so i dlike this to be as fast as possible, cause we need to go sleep too. in case of a failure does this affect warranty? the cache ssds will be on raid 1 and the 6hdds will be raid 6. i dont even think of loosing any data.
As I suspected, when I ripped out the Synology version of Plex from my DS1821+ and reinstalled Plex on my Windows 10 workstation (media files are on the DS1821+), it runs perfectly. We have been running four iPad watching four different shows (for over two and a half hours now), with perfect results. Seems that the Synology version of Plex is garbage. Plex is great, but they need to fix the buggy Plex for Synology version.
couldn't you just install docker on the NAS, and then install plex via docker? All still running happily on the NAS.
The limitations are clearly documented in the manual. I agree, it sucks. I'd never recommend someone running a large Plex install on a storage appliance like this. Don't blame the platform when you didn't RTFM though.
1st view .... woohoo! Bucketlist, tick.
Can I run 2 4k movies on at the sametime on Synology DS1621+
Wirelessly
You forgot to mention essential point Hybrid Raid will limit the raid speed of 1 drive compare to traditional raid 5 or 6, which means hybrid raid is good for storage efficiency not for performance, to sum up if you're using NAS as back up drive than hybrid raid is fine but if you're accessing your project from NAS directly than you should stick to raid 5 or 6 to make use of multiple drive speed.
This is not true. I have 4 drives in SHR-1 in an RS1221+ (soon to be migrated to SHR-2 when I get 4 more drives), and they consistently hit write and read speeds higher than 350MB/s when making internal operations.
@@sopota6469 you're still will be using one drive speed, bottlenecking with one drive speed, whereas your bottle neck should be limit of your network speed which is usually 10gb ethernet close to 950 mb/sec
Hi I need your help , which one has usb which we can used for file transfer not extended storage you mention it in one of your video but I lost it
He never helps
no plex transcode …
Does it run unraid? :D
If I populate one of the bays with and ssd, can I then use it for caching ?
Yes. For read AND write caching, you need 2 SSDs though
@@kokomcneal6197 ah, so one nvme is for write cache, and the 2nd for read cache? (or the other way around, but...) Any suggestion on advisable size of them?
I think both SSDs are 50% read and 50% write cache each. This way one does not loose any data when one Ssd dies. I have 2x 512GB. I guess it is overpowered. There is a tool in the Ssd Cache menu to help estimate the best size for the cache
DSM told me that it could only do read cache with one cache drive and need 2 for read and write.
Okay i got my 1821+ now and the improvement between DS918 vs1821 ise HUUUUGE
That is quite a jump there!
I wouldn't take a Synology NAS if it were free. The company's support policy on 3rd party hard drives stinks and they pretty much lock you out of using 20TB+ drives from Seagate, WD, or Toshiba if you want Synology technical support for your NAS. I ended up buying a QNAP 873A.
wtf is it?
