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.

Vertex 4

Above Vertex 4 256GB - The file test is showing advertised improved performance.

Vertex 4

Above Vertex 4 512GB

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.

As you can see, the SSD was a little fragmented after many benchmarks tests. Some say you need to erase the SSD, we say... that's real-world performance right there.

Vertex 4

In the second series of HD Tune tests with the original release we  averaged out roughly 186/sec on sequential reads for the 512GB model and 175MB/sec on the 256MB model.

The new firmware just obliterates the original performance numbers, both SSDs now show increased read performance in the 332 MB/sec range.

Vertex 4

Write performance increased marginally, but with a good 350 MB/sec, that's still the fastest SSD performance we have ever tested.

Vertex 4

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 albeit nothing dramatic.

Vertex 4

Overall great write IOPS performance as well. Roughly similar results as with the original release firmware.
