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.
When looking at the chart, it's important to keep in mind that only the same capacity sizes should be looked at together. Larger drives, especially those based on SandForce controllers are able to stretch their legs a little further just like a taller runner compared to a shorter runner. In these tests we focus on the 4K and NCQ performance, the three bars at the top of each group.
The Pyro SE with synchronous flash shows good scaling as commands are stacked in the 4K size. Starting out with just under 40MB/s with a single command and then achieving nearly 60MB/s at 4 depth is a nice increase. The highest queue depth tested, 32 commands shows an even larger increase; nearly 125MB/s.
Larger capacity drives are able to scale better at high queue depths, but the 120GB models have better single command performance when writing data. Here we see the Pyro SE hitting 131.2MB/s and then climbing to around 170MB/s when the write commands are stacked.
