QNAP QM2-2P-244A and Samsung 860 Evo 500GB

Post by potatonator » Fri Jul 24, 2020 9:18 am

Hi,
new 653D, latest QTS, all working fine with WD Red 4TB.
I bought a QNAP QM2-2P-244A Dual M.2 22110/2280 PCIe SSD Expansion Card and 2 X Samsung 860 Evo 500GB M.2 SATA III 6GB/s V-NAND SSD MZ-N6E500BW which according to the compatibility check should work fine.
When I installed it according to the instructions, the expansion card shows up, including fan speed etc. but the SSDs don't show. Am I missing something or do they need to be initialised somehow?
thanks in advance for your help
regards

Hi there you need M2.NVMe SSDs for this card, but your are using M2.Sata3 SSDs.
M2 ist just the common physical connector, but it can use different drive interfaces:

another question, the SSDs I can find here in Australia all say Samsung 970 EVO Plus 500GB M.2 NVMe SSD Samsung 500GB SSD, 970 EVO Plus, M.2 2280 NVMe PCIe Gen3 but the QNAP specs for the card are: PCIe and Lanes: PCIe Gen2 x 4

Is that SSD comapatible?


The compatibility checker doesn't work for me to check comaptibility of expansion card and SSD, only SSD and NAS and expansion card and NAS

PCIe is backward compatible e.g. PCIe 3.0 Devices run in an PCIe 2.0 Slot@ PCIe 2.0 speed...

I'm using a QM2-2P-384 with 2x 1TB Samsung EVO970 (RAID1) on a TS-677.
Qnap compatibility checker also gave me nothing on PCIe SSDs -> went for Samsung EVO 970 as i figured that QNAP couldn't ignore the market leader.

No Problems so far...
