Flagship solid state drives from OCZ – Vertex 4 – underwent yet another spec modification caused by the release of the new firmware version 1.5. Therefore, we decided to retest the “updated” Vertex 4 SSDs and try to figure out the reasons behind the notorious performance drop after filling up more than half of the available space.

File Copying
We use AS SSD version 1.6.4237.30508 test to benchmark the speed of copying files within a single partition the size of the whole SSD. The SSDs are tested in their steady state.



The Vertex 4 series could be expected to win this test. As we noted earlier, they are very good at writing, which explains their high speed of copying.
