I now have two of these boxes in service as 10Gbe multi-user video production file servers. Configured as 12x 16TB RAID6 (Note SHR is not available on this model), with a small SSD cache on both. Let me say first. These things are fast! Getting consisted 400-500 write and 900-1000 read with multiple users connected and using 4K ProRes bandwidth. DSM is s fairly easy to use, but AD has not worked on either box, even though we have no issue with it on Synology DS products.Major concern: Synology seems to be limiting their compatibility list on the newer products to favor their HDDs and other I/O devices. The 16TB Exos drives we are using are fully compatible with the 2418 (4 year old model), but they are not compatible with this box.

Active SMART monitoring is available on the old box, but it has to be run manually on this. I was able to schedule it as an email notification check once a month at least. Hoping Synology will not be so anti-competitive in the future.

I purchased this RS3621xs+ to replace my RS3617xs+. It was supposed to be the next model in the line. When I migrated my drives from the old to the new it informed me that the drives were an unsupported model. When I looked up the RS3621xs+ it says it supports 7 specific models of 3.5 hard drive, 3 of them Synology Brand. My RS3617xs+ supported hundreds. I would pass on this model and choose one with greater compatibility
