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.

Now this one is funny ... the numbers are so high that the field does not scale properly anymore. So top the left where you see 500 in the top, that's 1500 MB/sec okay ? :)

Alright, HD Tune PRO. 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 300MB/sec. Maximum peak writes are just over 1150 MB/sec with nearing 1400 MB read peaks, this is 100% as advertised.

Again, all the way to the left .. the numbers are cut off, that reads 500 -> 1000 -> 1500 MB/sec.

One of the more dirty tests then, in HDTune we average out roughly 454MB/sec on writes. We peak to roughly 576MB/sec, this is an immense task and test alright.

Your average SATA 6G based Vertex 3 or something similar would push roughly 340MB/sec on sequential writes/writes.

Write performance then, once we start to measure write performance we see figures reach a continued write performance averaging out at an average of 409 MB/sec with peaks to 554 MB/sec.

HD Tune Pro allows random access, read and write testing, a feature not available in other software tools. Check out the 1MB READ performance topping 1137 MB/sec. In bold comparison, a fast OCZ Vertex 2 SSD would push 260 MB/sec here.

Overall great write IOPS WRITE performance as well. We get 50MB/sec on 4KB files returned which is quite nice. Once we go larger in file-size and look at 1 MB performance, things pick up quickly again as we start to peak to 1044 MB/sec.

Think about it, each second this drive can write 1044 files with a size of 1 MB ... each second.
