Good news for anyone who has been following the recent reveal of Synology enabling M.2 NVMe SSDs as Storage Pools (covered previously here on NASCompares in this article) as it appears that the new feature is active on the Synology DS923+ NAS (released Nov 16th 2022). A recent update in DSM that, at this time, appears to ONLY be available for the DS923+ has allowed the two M.2 2280 NVMe SSD bays that were traditionally ONLY for caching to now be usable for storage pools. Full testing of this (as well as further updates to this article) will arrive very soon here and on youtube, but for now let’s discuss the M.2 NVMe Bays that you can use (bandwidth/speed), as well as the process of using the m.2 NVMe SSDs as Pools in the Synology DSM Storage Manager.
Note - Article Updated with information on M.2 NVMe SSD Compatibility, whether you can boot DSM from the M.2 NVMe SSDs and an update on the architecture of the PCIe Gen and Speed of the bays on the DS923+ NAS.

The 3.0×1 speed is likely a hardware limit due to the way Synology designed the pcie lanes on the board. I am mostly disapointed in their clearly artificial software hobbling of 3rd party drives.
The R1600 cpu has PCIe 3.0 x 8, PCIe Bandwidth: 7.9 GB/s,
8 lanes is used up pretty fast even with one lane per drive plus one for each external port... and any pcie expansion chips will funnel several devices into fewer lanes anyway (Not a bottleneck for slower or sporadically accessed devices, but lane layout is important.)

Hey, I'm planning a couple of Windows VMs on a 1821+ to manage the remote backups and my plex server. Is it better to use the NVMe as storage pool for the VMs or as a cache for the main big storage pools?

[@juebaitube]

Thank you. That was very interesting 😊.

[@Tru3Tech]

Installing plex server or VMs on m.2 storege pool, can it be done? Or on the m.2 volume you can only hold files and folders

[@lentilgod58]

So, not possible on ds920+?

[@randomity655]

How much impact would M.2 NVME Gen4's make? I'm thinking about either a QNAP TVS-h474M.2 (2 x M.2 2280 PCIe Gen3 x2 slots) or TVS-h674 (2 M.2 2280 PCIe Gen4 x4 slots)

[@dougrohde3598]

Randomity, where have you see those two models for sale?

[@marcusschmidt5103]

is it possible to use the m.2s as a art of ram to bring in the data via 10gb and then atomaticly mirrow this data to 10tb internally to wd reds 10tb?,i only thinking🤔

[@Scorpan]

That's is probably write cache you want. Look deeper into that

[@marcusschmidt5103]

@@Scorpan i have 2 m.2s for r/w cache istalled.the idea behind my question was ,the r/w cache is a good thing,but my idea was to use both of the m.2s as a drive,then my 10gb network is capable for full networkspeed instead of the bottlenecking from my wd red pros if i write direktly on the hdds+because of that i have named last time the m.2s as"an art of ram"after fullspeed networkdataspeed to the m.2s as a shared folder/with full 10gb speed)was my real question if i can automaticly in lower speed archive this files from the md2s automaticly on my hdds without givin a new task+that was my real question in order of atomatism.
