CrystalDiskMark is a disk benchmark software that allows us to benchmark 4K and 4K queue depths with accuracy.


Key Features:-


* 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.




Looking at 4K performance through the throughput glasses, we see that Extreme II is so close to 40MB/s at QD1. With a little tuning, I bet SanDisk can break the 40MB/s mark in CDM's 4K read test. Extreme II scales really good with additional queue depth read requests.




4K write performance scales well as the queue depth increases. Extreme II is still in running with the lead pack, but the results are not as impressive as the other two tier 1 SSDs.
