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 Extreme PRO - 480 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 250MB/sec. Maximum peak writes are at 510MB/sec write while touching 500 MB read peaks. 

In HDTune above we average out at roughly 455 MB/sec on sequential reads. That's the fastest we have ever recorded for a SATA3 SSD.

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 427 MB/sec. I'd say that is pretty darn good.

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 500 MB/sec depending on the model.

Overall average write IOPS performance as well. We get 296 MB/sec on the 1MB files. So each second this drive can write say 296 JPEG files with a size of 1 MB, per second for the 480GB model.
