CrystalDiskMark is a disk benchmark software that allows us to benchmark 4K and 4K queue depths with accuracy.
* Sequential reads/writes
* Random 4KB/512KB reads/writes
* Text copy
* Change dialog design
* internationalization (i18n)
Note: Crystal Disk Mark 3.0 Technical Preview was used for these tests since it offers the ability to measure native command queuing at 4 and 32.
CDM really shows us the balance or, in this case, imbalance of the drive. The M6e delivers amazing sequential performance, but the random reads are down compared to the best SSDs in that category.
Again, the sequential performance, this time in writes, is higher than everything else is, but the random 4K performance is down to many of the other drives. The SanDisk A110 delivered higher 4K writes than the Plextor M6e, and that surprises us since the M6e is faster in many tests.
The M6e is still very early, not even available in the US yet, so Plextor may still have some firmware tricks that increase random performance later on. On the next page, you'll see that Plextor did manage to balance performance.
