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 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 250MB/sec. Maximum peak writes are roughly ~500 MB/sec write and 525 MB read peaks.
For a non RAID storage unit that's just sick.
In HDTune we average out roughly 285MB/sec on sequential writes. We peak to roughly 360 MB/sec, remember that this is an 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 288 MB/sec with peaks to 358 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 465 MB/sec. In bold comparison, a fast OCZ Vertex 2 SSD would push 260 MB/sec here.
Overall very nice write IOPS WRITE performance as well. We get 54MB/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 420 MB/sec.
Think about it, each second this drive can write 400 files with a size of 1 MB ... each second.
