CrystalDiskMark is a useful benchmark to measure theoretical performance levels of hard drives and SSD’s. We are using v6.0.

Intel's 3D XPoint memory is all about very high random performance at low queue depths, particularly read's, something perfectly illustrated by the two sets of CrystalDiskMark results. At a QD of 32 the drive sits behind the Plextor M9Pe(Y), the Corsair Force MP510 and Samsung's SSD970 PRO.

However, testing the drive at a QD of 1 proves the effectiveness of 3D XPoint memory with a stunning read test result of 268.8MB/s, three and a half times faster than the nearest NAND equipped drive – Intel's own SSD760p.
