CrystalDiskMark is a disk benchmark software.

Key Features:-

* 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.

Here we see why the enterprise class drives do so well in the server tests. When piling on tasks they make really good use of the number of channels inside the controller. That said, the Toshiba controller found inside the Kingston SSDNow V+ Series seems to run dry of extra bandwidth when more tasks are put in line.

The older drives were not tested with version 3.0 Technical Preview.

When it comes to writing data at 4K with various QDs, once again we see the V+ not effectively taking advantage of prioritizing traffic like the other next gen and enterprise drives. Looking at the 4K numbers of the Indilinx drives, we see that the V+ doubles and in a couple of cases quadruples the 4K write performance of the current industry standard.
