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.
The RunCore T50 mSATA SATA III drive only uses four flash chips so it is at a disadvantage in some tests even though the chips are denser than what we'd see on a 2.5" drive with up to sixteen chips. The drive also uses asynchronous flash and not the higher rated synchronous flash. This shows up in our tests where incompressible data is used. Even with the asynchronous flash the T50 produces good 4K read results that scale well when the commands are stacked using native command queuing.
The T50 gave us predictable performance in the 4K and 4K NCQ write tests. The smaller SF-2200 Series drives (those under 240GB) hit a wall as seen with the Vertex 3 and RunCore T50. This wall keeps going up as firmware gets better, but the T50 manages to break the 180MB/s mark, though not by much.
