I've had this drive for about 18 months without problem. In the manual for the motherboard it states that you can't use a PCIe M.2 NVME and any device in PCIe slot 5 (which will be disabled if a PCIe M.2 NVME is installed). I have a Soundblaster X-Fi Titanium in this slot. Just this week, the SATA Crucial M.2 SSD disappeared from device manager on boot into Windows 7 -- along w/all partitions I had on the SSD. When I checked in the BIOS, it states PCIe slot 5 AND the M.2 slot are populated by my Soundblaster card. The Soundblaster card still works. Nowhere in the motherboard manual does it say I can't use PCIe slot 5 and a SATA M.2 SSD, but could this have caused the failure of the Crucial M.2 SATA SSD?
