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.
Since CDM literally killed two other SATA DOMs we've tried to test in the lab, I had to see how extreme Mach Xtreme made these drives. All three drives passed the read and write test without catching on fire, or dropping the SATA connection.
The 4K write performance may seem low, but it's important to keep in mind that DOMs are not built for this kind of workload. Most make it in write once, and read many configurations like industrial PCs, routers, firewalls, domain controllers, and so on.
