M2 SSD not visible.

I just Upgraded from a TNAS F4-210 to a TNAS F2-423. I'm trying to use a 60gb m2 SSD to increase performance, but the terramaster does not recognize it as being installed.

Any tips or tricks I need to know about to get this to work? I noticed there were 2 unlabeled m2 slots; If only one is used does it need to be installed in a specific slot?

My m2 is also shorter, and there's no way to screw it in to make it fully secure, so I'm using electrical tape.

Only use a compatible SSD as: viewtopic.php?f=82&t=3532

Really; That's an answer! We have standards for a reason. An m.2 socket should work with an m.2 device. What devices don't work, why?
Why is there no way to secure a shorter m.2 drive into the board?

Your SSD needs to be M.2 NVMe 2280 SSD (M key) and a recommended model. If you do not know what is M.2 NVMe 2280 SSD (M key), I can give you some references. Here is an article that may be helpful. https://www.atpinc.com/blog/what-is-m.2 ... y-socket-3

So the M.2 drive I have doesn't work because its M.2 SATA (not NVMe) and its size is 2242 (not 2280)?

Is there any limitation or benefit of going with gen3/gen4?
Where can I find more information on how the M.2 nvme drive can be used as a cache? The documentation that came with this device is non-existent.

The posts to secure any other size m.2 drive are only silkscreened on their internal board, with no means to actually attach anything other than a 2280.

The Celeron N5105/N5095 SoC used on this device, only has 8 PCIe Gen3 lanes, which are all consumed:
  • another 2 for the NVMe m.2 slots (×1 each)
  • the lastly, SATA for the mechanical drives, provided by a controller on the backplane over a PCIe ×4 connection.

It's only electronically PCIe Gen3 ×1, so it's a waste to buy & use any ×4 and definitely any Gen4 performance drives.

Technically any PCIe Gen3 2280 NVMe m.2 should function.

Aim for a PCIe Gen3 ×2 2280 m.2 NVMe SSD.

If you are going to purchase outside of their previously linked compatibility list, just ensure you are purchasing from a retailer that has a good return policy, should the drive not work & you have no other means to make use of it on a different system.

Terra-Master is not the size of its competition and thus doesn't currently have the resources to dedicate to testing every commercially available drive.

The specifications page is fairly detailed.
