Yapt (yet another performance test) is a benchmark recommended to me 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.
The OCZ Apex has a good showing throughout the four different testing scenarios using Yapt though is never quite fast enough to WIN any of them. The random read test definitely belongs to the Intel X25-M though the Apex is clearly better than any other drive we tested. The Intel X25-M is also faster in random writes and the JMicron-based Apex is one of the slower options for that. The two sequential tests again are pretty good for the Apex 250GB as it is able to keep up with the top drives in reads and have a healthy second place finish under sequential writes.
