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. 

HD Tune Pro allows random access read and write testing, a feature not available in other software tools.

Overall average write IOPS performance as well.
