Not sure if this drive is on the QVL.. Didn't see an NvME list..If I had to guess, I'd say its the drive. Other options:http://www.goplextor.com/Support/DownloadsI saw FW 1.05, but I strongly caution you regarding upgrade. If your system is working.... I wouldn't upgrade the MB BIOS or FW on the drive unless you are absolutely sure it will fix or address an issue. If you are getting expected I/O from the drive, I'd stay where you are. Your call.
