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 random read test is by far the best showing for the Intel X25-M 80GB SSD as it reaches over 260 MB/s across all data sizes while the sequential read test is just as fast but has a closer competitor with the VelociRaptors in RAID 0 mode. The write speeds are slower as we continue to expect with the SSD products of this generation but we can see the random writes benefit from fast access times and are still able to beat out all the standard platter-based drives. The X25-M is in the mix of the sequential writes test but can’t stand out amongst the crowd.
