QNAP Expanision Card ? - Enquiries - 02-28-2020
Hi Robbie
I am not a pro IT person like yourself and followed your advice and purchased a TS-251D and have been very happy
I am looking to expand the NAS with some SSD cache and I am confused about the difference between QM2-2P-244A vs QM2-2P-344 cards except that the 344 is slightly more expensive.. :-)
I just want to expand NAS with 1 or 2 SSD's and not bothered about 10GBs RJ45 and confused about the difference between the 244 and 344
Appreciate your feedback if you get chance?
Thanks
Charles

QNAP Expanision Card ? - ed - 02-10-2021
Here is a decoded version of a model number:QM2-2P-344Q - QnapM2 - m.2-2 - m.2 slotsP - nvme-3 - gen 34 -x 4 lanes4 - 4 internal x lanesThe speed difference between these two cards is as follows:QM2-2P-244A -> 2GB/sQM2-2P-344 -> 4GB/sThe speed of TS-251D PCIe is around 2000MB/sSo I would recommend QM2-2P-244A unless you would move this card to a future NAS. Then Gen3 would be useful.I hope this helps.
