SSD Performance HD Tune PRO

HD Tune Pro 4.5

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 figures coming from the storage unit.

First off, a file test. We fire off 64MB of data comprising out of sizes ranging from 0,5 KB to 8 MB. Check it out. As you can see once we pass 32KB file size, the drive kicks in hard already pushing over 200MB/sec. Maximum peak writes are roughly ~660 MB/sec and 680 MB read peaks.

In HDTune we average out roughly 295MB/sec on sequential writes. We peak to roughly 403 MB/sec, remember that this is a immense task and test alright.

Write performance, we know that the NAND memory is slightly slower overall. Once we start to measure write performance we see figures reach a continued write performance averaging out at an average of 250 MB/sec with peaks to 341 MB/sec.

HD Tune Pro allows random access read and write testing, a feature not available in other software tools. Check out the 1MB performance topping 656 MB/sec. As comparison, a blazingly fast OCZ Vertex 2 SSD would push 260 MB/sec here.

Overall very nice write IOPS performance as well. We get 37MB/sec on 4KB files returned which is quite okay. Once we go larger in file-size and look at 1 MB performance, things pick up quickly again as we start to peak to almost 620 MB/sec.
