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.
Intel has obviously worked hard on real world random write activity. There is a noticeable jump in performance, especially in random writes. Our Yapt test cuts off at 64K, but you can see how the Vertex was already falling off in performance at that point, while the X25-M G2 was still hugging it’s 80 MB/sec limit.
