Dear Bob, I need help. NAS setup

well - Synology has removed the DS1821+ from their website, so I cannot tell you what is the largest supported drive. On the current models - DS1823xs+ and DS1825+, they are only officially supporting Synology drives, not Seagate or Western Digital or Toshiba. There were some drives that were suppor

Setting up a NAS - Who to Hire?

you are not doing anything with a 4 drive NAS. the suggestion below of the 1821+ is a good suggestion if the DS1821+ was still being made, but today it's the DS1825+ or DS1823xs+. And for these models, you have to use Synology branded drives, which are double the price of a Seagate EXOS or Western D

NAS setup for small team, hybrid workflow

Good morning. Your "Synology rep" - really ? using an iSCSI LUN has nothing to do with remote editing. For your simple application - all you need to do is connect via the built in SMB network protocol, which is both on your Mac (and any office PC) and the Synology. To do professional video editing,

State of UGreen vs Synology

Yeah, i got a 4800+ at the kickstarter. It really is kinda basic hardware compared to computers out today, but its so much faster than the synology in every measurable way. The 10gbe network is a must have. I genuinely think that Synology management has never used their own products. Its been great,

Synology Migration - HOWTO

It being slow seems to be a synology limitation. I had overseer as the only container running, a quad core ryzen CPU, 500GB of NVME cache and 64GB of RAM in my DS1821+. Still performed awfully, moving to another box made it lightning fast.

guys, i need more storage

I have DS1821+ with 2 expansions, later I found out, the link cable is the biggest "Single Point of Failure". One move, a cat or a bad cable. ALL data is unrecoverable, because you lose more than 2 drives at once. A rebuild is not possible. So, you can't span your volume over the expansion without t

Stick with 6×4TB SSDs or move to large HDDs for a Plex NAS?

SSDs are wasted on a NAS, don't bother. The bottleneck is your network connection. Its like taking a 5 gallon bucket and dumping it into a drinking straw. Its not going to go through any faster than a regular water bottle. If you have SSDs laying around then use them, but you will get the same speed

Running two servers?

Seems completely pointless to me. If you're transcoding the Synology will struggle. If you're not transcoding I'd say your upload speed is going to be the bottle neck. I have recently pulled my Plex server from the DS1821+ and put it on an i5 9500. The difference is night and day and I hardly even w

Change to NAS?

I also have the same Beelink EQI12 you have with a Synology ds1821 for storage. The performance bump I got from moving Plex from the ds1821 to the Beelink was well worth it and I wouldn't go back. The only mod I made was switching from Windows to Ubuntu on the Beelink.

FYI: DSM 7.3 Breaks Plex (and the fix)

I had similar issues with "7.3.2-86009 Update 3", worked fine with "7.3.2-86009 Update 2".I'm running plex server version v.1.43.0.10492-121068a07 (last available to date) and also upgrading to the beta (v.1.43.1.10540-3972d551c) did not solve this. I use my plex daily and found this really frustrat
