HD Tune Pro gives us accurate read, write and access time results and for the last couple of years has been gaining popularity amongst reviewers. It is now considered a must have application for storage device testing.
In our early tests we're looking to break the drive in while measuring peak performance. In HD Tune Pro we averaged just over 430MB/s read speed with an average and minimum performance very close to the average read speed.
Writing for the first time across the drive produced an average write speed of 417MB/s. The maximum sequential write speed wasn't much higher, just 423MB/s. The minimum dropped down to 378MB/s and that dip came from a single blip.
We've ran HD Tach for years right after HD Tune Pro, but rarely use the data. For the most part the test aids in pushing the drive into a deeper steady state for our real-world tests. I'm putting HD Tach in the game this time to show a couple of patterns. In the test above we see the performance of the drive after the six HD Tune Pro tests. As you can see the performance is all over the place in both reads and writes. In three places we see write speed dip below 100MB/s.
After writing sequential data to the drive we see the read performance level off at roughly 170MB/s, but the write speed dips all the way down to 50MB/s in some places.
