SSD Performance HD Tune PRO

HD Tune Pro

A new test added to the benchmark suit is HD Tune Pro, this was actually a user request which we are more than happy to comply with. Tune Pro is a hard disk utility and benchmarking utility for Windows. This tiny application allows you to scan your hard drives in search for errors or take a deeper look at several performance figured coming from the storage unit.

So here we measure linear read performance of the SSD and as you can see we average out at roughly 217 MB/sec with peaks towards 218 MB/sec, stunning performance you'll agree with me. Your Average HDD would do 45-65 MB/sec here.

A massive flatline ... we do feel we again see a controller limitation here.

Write performance always paints a different picture, yet even here once we start to measure write performance we see figures reach a very high plafond. (Editor: Totally had to google "plafond." )

The continued write performance is really good but we average out at roughly 183 MB/sec with peaks to 200 MB/sec, again .. we are talking pure, raw, unadulterated write performance here. Your regular HDD would do what ... maybe 50 MB-sec continuously with the WD VelociRaptor hovering at maybe 100~120 MB/sec.

The latest edition of HD Tune Pro allows random access read and write testing, a feature not available to other software tools. And this is certainly interesting to observe.

Overall extremely good, though the random IOPS performance seems a little on the low side. This benchmark unfortunately is not precise measurement. Each run differs a little with fluctuation up-to 10-20%. Therefore we run it three times and use the last score.

Here we can see the write performance measured in IO operations per second, higher is better. We see that the drive has significant more issues with random write performance. The results however are very satisfactory.
