HDTach results

Website: HD Tach 3.0


The burst results are behind that of most hard drives out there, including the JMicron based SSD designs. It doesn't mean a whole lot to real world performance but it's a slight disadvantage for responsiveness of the OCZ here.


Average read speed across the drive is excellent, with the newer v1.1 firmware managing 221MB/s across the entire drive, in comparison to the slightly faster Intel X25-E and the X25-M using its original firmware (updating to the 8820 firmware seems to have slowed the X25-M slightly).


Wow! Out of the box the Vertex is ludicrously fast when it comes to sequential read speed across the drive, with a scorching 153.5 MB/s! However, in the latest firmware this seems to have been dialed down a little to allow for read/write latency improvements, but even then it is still faster than any other SSD we've yet to test using the HD-Tach write speed test (although the X25-E has notably not been tested since it was returned before we got the software).


Finally, random access times are predictably fast, with the OCZ Vertex managing access times of sub 0.1ms using either the 1275 or 1.1 firmware, matching the Intel X25 drives and hundreds of times faster than conventional hard disks.
