Yapt v0.3
Yapt v0.3
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 showed some of the same write speed inconsistencies seen with the RAID during our IOMeter tests. Lets hope future versions of the Intel RAID drivers can overcome these random write scaling issues (and hopefully add TRIM forwarding to arrays!). Reads were still strong for the array, hitting 350 MB/sec for the pair of Kingston 40GB drives.
