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 4K IOPS results carry over to CDM. Here, we see the 4K QD1 read at 24 MB/s. In this test, we get to see the full sequential read speed, which is over 540 MB/s. The Q Series Pro does the same thing that the modern Vertex and Vector drives do; the QD1 read speed is limited, so another task can take place without the drive feeling slow when multitasking.
Again, the IOPS performance results carried over well in CDM, where we see the MB/s. The Q Series Pro scales well from QD1 to QD4, but the drive plateaus early.
