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.





Reading sequential data from the drives at a single queue depth resulted in an average speed of 465MB/s. This is a little faster than the non-Pro Samsung drive and faster than Vector 512GB. To be fair, we want to point out that OCZ limits their single queue depth performance to allow for multitasking overhead. It takes a queue depth of 2 to reach OCZ's maximum sequential read performance.




Writing sequential data is around 3MB/s faster on the 840 Pro when compared to Vector in this capacity size. That's a very close score for two drives with completely different designs.



HD Tach - Sequential Write Performance after Random Writes




Writing sequential data after a controlled number of random writes doesn't affect the larger drives as much as smaller drives. The 840 Pro fairs very well in this custom test, the average write speed with 128KB blocks was just over 391MB/s.
