Version and / or Patch Used:3.0 Technical Preview
CrystalDiskMark is a disk benchmark software.
* Sequential reads/writes
* Random 4KB/512KB reads/writes
* Text copy
* Change dialog design
* internationalization (i18n)
Note: Crystal Disk Mark 3.0 is not available to the public yet, but the Technical Preview does allow us to test 4K performance at queue depths of 4 and 32 in addition to 1. The current release Crystal Disk Mark only shows us QD 1.
In CDM we look at 4K and 4K with queue depth performance. The 4K read performance is solid and right where we expect it to be, but the QD:4 and QD:32 are a little lower than the Vertex 2 120GB drive we tested. This is most likely due to the latest firmware found on the Zalman. Later in this review we will see if this level of performance hampers the real world tests.
The 4K and 4K at depth write performance was nearly exactly that of the Vertex 2. The Zalman N Series 128GB drive is able to write data very quickly at this block size.
