Review on 💾 Enhance Your Storage with QNAP QM2-2P10G1TA PCIe Expansion Card: 2 x PCIe 2280 M.2 SSD Slots by Jimmy Scaturro

I encountered data corruption issues when using this card on a 10Gig network. I did some tests and found that the files get corrupted about 20-40% of the time. 2, 3, 4, 5 and 10GB files, then transfer them and compare the sha256 totals before and after. I've found that every time even one of them has a different sha256 sum (and gets corrupted). I installed QXG-10G10. 10GB card and moved my entire network to it and everything works as it should (no harm). This is a relatively new product (PCI NVMe version) and I think that's because the NVMe cards and the 10G network both use the same bus, which causes problems in data transfer. I gave it 2 stars because after adding another NIC at least the NVMe slots worked correctly. FINAL THOUGHTS: This is a new product and some crashes are to be expected, but on a storage platform that crashes (especially if both the platform and the card are from QNAP), such a crash is unacceptable. Had I known, I would have just ordered the NVMe card and bought the 10G card separately. My machine is a TS-1277 with the latest (current) firmware.
