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.
Yapt is a good test for bulk file copy activity, and it gives us another data point to compare these units. While the Ibis can’t turn on a dime like the ioDrive, when you hit it with a purely sequential write stream, it’s able to squeak by a card nearly 10x the price!
