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 get to look at the 4K and queue depth performance. This is one area that I thought the new 3.5" design would start to pull away from the 2.5" model, but it looks like I was wrong. For the most part both drives run nearly identical when measured at the same 120GB capacity.
Keeping with the theme so far, the OCZ Vertex 2 3.5" drive also matches the 2.5" model in 4K write speeds at depth. Let's get to the real world tests and see what happens there.
