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 - The file test is showing advertised write perf, slightly slower read perf though,

Above Vertex 4 512GB - quite good numbers

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.

In the second series of HD Tune tests we average out roughly 184MB/sec on sequential reads for the 512GB model and 160MB/sec on the 256MB model.

Now we tried on several systems with MS AHCI and Intel SRT AHCI mode but the results remained the same. We have no idea why the read test is so much off in this benchmark. Especially when you look at write performance:

See that's quite the opposite. Write performance is at an average of 344MB/sec and 322MB/sec for the 512GB and 256GB models. The 512GB model peaked to a maximum of 415MB/sec and 353MB/sec for the 256GB model.

HD Tune Pro allows random access read and write testing, a feature not available in other software tools. Again we see good, but slightly average read results here, and again in write performance you'll be flabbergasted:

Overall great write IOPS performance as well. We get 455MB/sec on the 1MB files. So each second this drive can write say 455 JPEG files with a size of 1MB, each second, on the 512MB model.
