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.
It's amazing how far 4K read and write speeds have went up over the last three years. When SSDs first started making it to mainstream users, 20MB/s of 4K read performance was enthusiast class. Now, 40MB/s is the magic number everyone is shooting for (as measured in this test, IOMeter results are a little lower).
The new firmware gives a slight performance increase in 4K writes. The increased performance scales well as queue depth is increased.
