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.
Moving over to 4K scaling queue depth, this time in MB/s, we see a repeat of what the previous page showed. The M5 Pro with firmware 1.2 splits the 840 Pro and Vector at lower QD.
Write IOPS are down compared to the other two tier 1 class drives, but IOPS is only part of the reason why we buy SSDs.
