SSD Performance HD Tune PRO

HD Tune Pro

HD Tune Pro is a hard disk utility and benchmarking utility for Windows. This tiny application allows you to scan your hard drives for errors or take a deeper look at several performance figures coming from the storage unit.
 

First off, a file test. We fire off 64 MB of data comprising out of sizes ranging from 0.5 KB to 8 MB. Check it out. As you can see, once we pass 16 KB file size, the drive kicks in hard, however we see a small dip at 32KB. Maximum peak writes are passing 520 MB/sec write while touching 500 MB read peaks.

In HDTune above we average out roughly 338 MB/sec on sequential reads. That's a little so-so. Barefoot controllers do seem to have a genuine dislike for this specific HDTune Read test. But writes on the other hand...

Write performance above then, once we start to measure write performance we see that figures reach a continued write performance, averaging out at an average of 429~430 MB/sec.

HD Tune Pro allows random access read and write testing, a feature not available in other software tools. Check out the 1 MB READ performance topping 494 MB/sec. That is very nice. Though positioned a little lower in the charts you need to be aware of the fact that the difference to the fastest SSD is only like ~20 MB/sec.

Overall remarkable write IOPS performance as well. We get 473 MB/sec on the 1 MB files. So each second this drive can write, say 473 JPEG files with a size of 1 MB, per second.
