My sm951 wont reach the full write speeds or read speeds. I get like 1578 read speed and 1271 write speed. I have a MSI X99s gaming 7, 2x 980ti, one WD HDD, 16gb G skill rip jaws ram and a 5820k with a noctuah nh-d15, and a asus dvd drive. Why am I not getting full speeds? I updated my Bios to the newest version. the sm951 is my boot drive.
