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.
This is where we start to see a divide between the really good SandForce based drives with synchronous flash and the Kingston SSDNow V+ 200 with asynchronous flash.
The single request 4K speed is pretty good, 32.3MB/s. This is in line with other SandForce based drives. When you start piling requests up though the performance falls and the V+ 200 is back quite a ways. This is less of a problem that you might imagine in a notebook used for business activities. Even a power user like myself doesn't reach high queue depths on my notebook when I'm using it for work.
The 4K write speeds when using incompressible data are in line with other SandForce based drives, even those with synchronous flash.
