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.
Incompressible read performance was also the exact same for these two Force drives. Just hang tight though as we are starting to get somewhere.
Ah HA! Incompressible write performance, like we said - intense loads! The sequential write performance is quite a bit higher with incompressible data, movies, music and such. When you are moving a large file around it's a good chance that the data is incompressible. The difference is roughly 50MB/s with the lead going to the Force GT 240GB with the 32 chip design.
The single command 4K numbers are identical, but when the commands start to scale up so does the Force GT over the Force GS 240GB.
