SSD Performance HD Tune PRO

HD Tune Pro

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.

Above Vertex 4 256GB - 1.4 Firmware

Above Vertex 4 1.5 Firmware a dip in the 256 / 512 ranges.

We tried this test multiple times even after a secure erase this would show up again and again. Overall though we reach higher peak performance though moving from the 450MB/sec range into the 500 Mb/sec ranges.

We fire off 64MB of data comprising out of sizes ranging from 0.5KB to 8MB. Check it out. As you can see once we pass 32KB file size, the drive kicks in hard, already pushing 250MB/sec. Maximum peak writes are nearing 500MB/sec. These dips are weird though.

In the second series of HD Tune tests with the original release we averaged out roughly 175mb/sec on the 256MB model. Revision 1.4 gave us a huge perf bump towards 332 MB/sec, but for FW 1.5 we have to give back a little and end close to 300MB/sec.

Write performance remains roughly equal to the 1.4 release with a good 350 MB/sec, that's amongst the fastest SSD performance we have ever tested.

HD Tune Pro allows random access read and write testing, a feature not available in other software tools. We again see a bump in performance with v1.5, albeit nothing dramatic.

Overall great write IOPS performance as well, with again a bump in perf with the 1.5 release.
