CrystalDiskMark 3.0.1 Results

CrystalDiskMark is an easy-to-run and quick utility to use to gauge a drive’s performance. It measures sequential read and write performance and random read and write speeds of random 4KB, 4KB (queue depth 32) and 512KB data.

The Plextor M5 Pro got off to a good start and posted very high sequential read and write speeds. Its sequential write performance was 13% faster than the even the fastest SandForce drive. Performance on the 4k workload was a little shaky as it posted fast read speeds but below par write speeds. On the 4k, 32 queue depth work load, which is a more accurate representation of everyday usage, it redeemed itself by recording speeds that surpassed every SandForce drive.

The Good
Very good Iometer performance
Overall performance shows lots of promise
The Bad
Erratic performance on Futuremark benchmarks and HD Tune
Firmware is troublesome to update
Firmware needs optimizing
Very pricey
