Samsung 840 EVO 500GB and 1TB Full Review - TurboWrite TLC
Yapt (yet another performance test) is a benchmark recommended by a pair of drive manufacturers and was incredibly difficult to locate as it hasn't been updated or used in quite some time. That doesn't make it irrelevant by any means though, as the benchmark is quite useful. It creates a test file of about 100 MB in size and runs both random and sequential read and write tests with it while changing the data I/O size in the process. The results are a good look at overall drive performance.
All Samsung SSDs perform well in Yapt, while the OCZ unit hit some sort of odd resonance with the differing block transfer sizes.
