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.
OCZ limits the queue depth 1 performance at 64KB, so the Barefoot 3 drives always have a poor showing in some of our early tests. This increases the user experience factor when multitasking as it keeps performance in reserve when transferring data.
Barefoot 3 also plays tricks on our sequential write test at 64KB. The first half of the test runs at very high speeds but then drops down to a low state for the second half. Since you will never write to the entire capacity of the drive at the same time under normal circumstances, this isn't an issue.
HD Tach - Sequential Write Performance after Random Writes
Here we see sequential performance after a number of random writes. This test uses 128KB blocks so we don't see the 50/50 split in write performance on this chart.
