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 64 MB of data comprising out of sizes ranging from 0.5 KB to 8 MB. Check it out. As you can see once we pass 32 KB file size, the drive kicks in hard, already pushing 400 MB/s. Maximum peak writes pass  500 MB/s write while touching 514 MB/s read peaks.


In HDTune above we average out roughly 460 MB/s on sequential reads. That's very good for this particular test. 


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 431 MB/s.


HD Tune Pro allows random access read and write testing, a feature not available in other software tools. Check out the 1 MB READ performance topping 513 MB/s. Again, impressive!


Overall remarkable write IOPS performance as well. We get 490 units per sec on 1 MB files.
