SSD Performance HD Tune PRO

HD Tune Pro

HD Tune Pro is an excellent utility, and one of the few to provide a visualization (of sorts) of what happened during the benchmark run. Since the write test on the random read side of things needs an unformatted and unpartitioned drive, we can only provide you the read results here. However, we have also run the more general 'file benchmark' run, which measures the drive not in terms of read/write performance, but also IOPs (Integer Operations per Second).

This... though, this was a weird one. The drive is clearly not faulty; however I was not able to run the File Benchmark test without encountering an I/O error. No matter what I did, or how I ran the test, this error kept cropping up, preventing the run going any further. However, from what you can see of the test, it was very odd, with very low performance at first, then very inconsistent performance. 4Kb random single reads were certainly lower on the PD400 than even the Seagate drive, though it was a little faster in 4Kb single writes. The test failed, seemingly, when the multi 4Kb reads/writes were attempted. The drive appeared to be working perfectly, though, and up until this point this was the only sign of any trouble. I wasn't especially worried about this, however, and it might well be a problem with the benchmark.

Next, we move onto the relatively simple 'AS SSD' benchmark tool.
