CrystalDiskMark is a useful benchmark to measure theoretical performance levels of hard drives and SSD’s. We are using v6.0 and v8.0
The Spatium M480 doesn't fare so well in the QD32 test of CDM 6 but looking at the benchmark result screens we can confirm and indeed better the official read figure of 7,000MB/s with a default test result of 7,115.8MB/s and 7,457MB/s when the drive is dealing with compressible data. Tested Sequential writes were a little short of the official maximum of 6,800MB/s at 6,731MB/s.

CrystalDiskMark 8 Real World Performance Profile
CrystalDiskMark 8 comes with a couple of interesting ready-made testing profiles as well as a dedicated NVMe setting. The best tested Sequential figures for reads, 7,398.32MB/s, more than confirms the official maximum figure of 7,000MB/s while the best Sequential write test result of 6,719.90MB/s is a little shy of the official maximum of 6,800MB/s.
The best tested random 4K figures in CDM8 for the drive are 661,885.50 IOPS for reads which confirms the official maximum for the drive of 650,000 IOPS. The best write score of 604,243 IOPS is a little short of the write maximum of 700,000 IOPS.
Looking at the CrystalDiskMark results screens we can see that the Phison E18 controller that the Spatium M480 uses is much more efficient when reading compressible sequential and 4K data at certain queue depths.
