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.
We measured 840 EVO mSATA 1TB at 46 MB/s 4K read using CDM. The drive scales well as the queue depth increases all the way to 400 MB/s at QD32.
The 4K QD1 write performance is amazing for an mSATA drive; nearly 143 MB/s. Just as impressive is the sequential write performance at both 128KB, and 64KB.
