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.


Sandisk Ultra II - 240 GB 

First off, a file test. We fire off 64MB of data comprising 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 passing 300MB/sec. Maximum peak writes are at 475 MB/sec write while touching 525 MB read peaks. 


In HDTune above we average out at roughly 426 MB/sec on sequential reads.


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 roughly 260 MB/sec. I'd say that is below average.


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 488 MB/sec depending on the model.


Overall average write IOPS performance as well. We get 213 MB/sec on the 1MB files. That is pretty dissapointing.
