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.
We have a winner... or at least a tie-err. The reference design is only the third 128GB class SSD to break into the 40 MB/s 4K read area. Many have tried, but few have succeeded. The drive scales well in 4K throughput when commands are stacked.
Looking at the numbers, we see the reference design is very close to the SanDisk Extreme II, the newest entry into the hyper-class SSDs with Vector and 840 Pro in the same category.
It's hard to believe that the Silicon Motion SM2246EN is just a 4-channel controller.
