CrystalDiskMark is a useful benchmark to measure theoretical performance levels of hard drives and SSD’s. We are using v8.0.
Using the default CrystalBenchMark 8 4K QD1 T-1 benchmark the FX900 Pro's result figure of 88.12MB/s for reads is good enough to sit the drive in the third spot in our results chart. The write result of 231.53MB/s isn't as strong in comparison with many of its competitors.
Looking at the benchmark result screens we could confirm the official read/write maximums of 7,400MB/s and 6,700MB/s with test results of 7,523MB/s and 6,705MB/s for reads and writes respectively. That tested read score of 7,523MB/s makes the FX900 Pro the fastest consumer Gen4 drive we've seen to date, although the write performance isn't as strong.
Switching over to the CrystalDiskMark 8 Peak Performance profile we could once again confirm the official Sequential read/write figures with test results of 7,479MB/s for reads and 6,709MB/s for writes.
The 4K test results are nowhere near as impressive with both reads and writes falling well short of the official figures. The 2TB FX900 Pro is rated up to 1344 K IOPS for reads and 1122 K IOPS for writes. The best read result we saw in CrystalDiskMark was 621,817 IOPS for reads and 503,628 IOPS for writes.
Using the Real World profile sees the drive sitting in mid-table with a Sequential read result of 3,837MB/s while write performance is much better at 5,667MB/s.
