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 get our first real look of incompressible performance with Daytona 240GB. The Intel 520 Series represents a typical LSI SandForce SSD with synchronous NAND and is our gauge now when looking at these products. Daytona manages to outperform 520 in 4K reads, but when we ramp up the queue depth, Daytona does ramp up with the workload.
The sequential read performance with incompressible data is poor to say the least. It's been a long time since we've seen a SSD not break the 250MB/s mark.
The incompressible write performance was a bit better than the read test.
