HD Tune Pro gives us accurate read, write and access time results and for the last couple of years has been gaining popularity amongst reviewers. It is now considered a must have application for storage device testing.





We were told the new firmware should increase sequential write speed and in some of our tests that was true. The single command performance, or 1 queue depth request still delivers around 300 to 310MB/s. We'll look at the multi-request reads a little later on.




The sequential write speed increased at peak and on average in this test across the disk. The annoying dip in speed right around the 70% mark is still present, but the 256GB drive goes back to full speed right away. In our testing with the 128GB Vertex 4 there is a loss of performance just after the dip, the larger drives do not suffer from the issue.
