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.
Here we look at 4K performance through the throughput glasses. At QD1 the Seagate 600 480GB delivers 32MB/s. That puts it with the Samsung 840 non-Pro and drives now repurposed for mainstream uses.
Single QD write performance was 117.9MB/s in our test. The drive scales well when QD increases up to QD32.
