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 in search for errors or take a deeper look at several performance figured coming from the storage unit.

HDTune is the one test that does not like the SF-1200. Weird anomalies, very average performance and even one test would not finishes.

So here we measure linear read performance of the SSD and as you can see we average out at roughly 214 MB/sec, okay performance you'll agree with me but not up-to par to what you'd expect with the S599. Your Average HDD would do 45-65 MB/sec here, with a WD VelociRaptor topping is off just over 100~120 MB/sec.

Write performance get's even worse, we know that the 34nm NAND memory is slower than Samsung modules. Once we start to measure write performance we see figures reach a continued write performance averaging out at roughly 149MB/sec, that I can not explain though. It's not consistent with the other benchmarks.

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. 30 MB/sec on 4 KB files is just great.

Overall very good write IOPS performance. We get 21MB/sec on 4KB files returned. Here however the benchmark would not finish properly. The HDTune results as such should not considered to be objective until either a software update fixes some issues, or perhaps on the SSD side a firmware upgrade solves it.
