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.
The RevoDrive beats the ioXtreme Pro by a fair margin on writes, but two SandForce units simply can’t provide the throughput to match the 700+MB/sec reads of FusionIO.
