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.
In this chart we have both the MyDigitalSSD BP3 with the Phison S8 controller on older programming and Toshiba 24nm and can compare the performance to the new BP4, both in mSATA form factor. The older model delivers better 4K read performance at QD1 and QD4, but the new 16K page size 19nm Toggle (on the BP4) delivers better performance at higher queue depths.
Both BulletProof mSATA drives show the same write performance brick wall, but the new BP4 has a higher ceiling when writing 4K data.
