HD Tune Pro gives us accurate read, write and access time results and for the last couple of years has gained popularity amongst reviewers. It is now considered a must have application for storage device testing.





In HD Tune Pro we had a bit of a hiccup at the beginning of each of our read tests and we never managed to sort it out. The dip was always at the same spot at the beginning of the test and even a secure erase couldn't resolve the issue.


The dip didn't have much of an effect on the average score as you can see in the results. We scored an average sequential read speed at 449MB/s with QD1.




The sequential write speed topped out at 361MB/s under the same conditions.



HD Tach - Sequential Write Performance after Random Writes




Here we see 128KB data size sequentially after hitting the drive hard with random data. We are looking at the flutter on the write speed and how low it goes. The Xtreme dips down to just below 200MB/s, but has an average write speed of 334.1MB/s.
