HD Tune Pro is another test we are using today. HD Tune is a hard disk utility with many functions. It can be used to measure the drive’s performance, scan for errors, check the health status (S.M.A.R.T.), securely erase all data and much more.
HD Tune testing reinforces the performance gulf between USB 2.0 and USB 3.0 with the drive delivering an average MB/s performance score of 72.4 compared to 30.3 in USB 2.0. The peak speeds were 85.2 MB/s in USB 3.0 and 33.2 MB/s in USB 2.0, again a significant improvement when moving to the new standard.
The next benchmark we want to use is CrystalMark which is a great test to measure various aspects of a drives performance, such as sequential read and write speeds and random 512kb, 4kb and 4kb (queue depth =32) read and write speeds.
Again we are seeing huge differences between USB 2.0 and USB 3.0 in the CrystalMark test with the drive recording a maximum performance level around 90 MB/s in the Sequential read test and only 34.12MB/s under USB 2.0 restrictions.
