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 Transcend SSD720 delivered a very good 4K read performance, just over 41MB/s. The scaling when the queue depths increase were nice as well with a 65MB/s 4QD and 222.5MB/s QD32 read performance.
In CDM's write test we get our first look at incompressible data writing to the Transcend SSD720. The 4K write speed recorded in our test was just over 131MB/s. The QD4 write jumped to 232MB/s and that went up another 12MB/s to 244.2MB/s in the QD32 test.
