CrystalDiskMark is a useful benchmark to measure theoretical performance levels of hard drives and SSD’s. We are using v8.0.
Teamgroup quotes Sequential read/write figures for the drive as up to 7,200MB/s and 6,000MB/s respectively. Using the default CrystalDiskMark 8 test we could confirm the official read figure with a result of 7,433MB/s. As for writes, the test result of 5,868MB/s is just a wee bit shy of the official maximum figure.
The read result of 83.06 in the default 4K QD1 CrystalDiskMark 8 test sees the drive into fourth place on our results chart.
Looking at all the CrystalDiskMark results screens we can see that the Phison E18 controller that the A440 Pro Special Series uses is much more efficient when reading compressible 4K data at lower queue depths.
Using the Peak Performance profile of CrystalDiskMark 8 we got a Sequential read score of 7,384MB/s, an increase of 184MB/s over the official maximum while the 5,866MB/s Sequential write score was 134MB/s shy of the official maximum at 5,866MB/s.
The Peak Performance profile also gave us the best random read/write figures we saw for the drive, but both the random read best (650.957 IOPS) and write best (541,979 IOPS) are way off the official maximum of 1,000,000 IOPS for both.
Using the Real World profile of CrystalDiskMark8, the latest T-Force Cardea A440 Pro Special Series drive produces a Sequential read score that is 1,201MB/s faster than the first generation TeamGroup Gen4 drive, the T-Force Cardea Zero Z440. Writes show an even bigger improvement at 1,362MB/s.
