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.
Our Yapt results for the OCZ Summit are very impressive and show it to be a truly legitimate competitor to the Intel X25-M. Random reads are fast for the Summit as it comes in behind only the Intel drive in raw performance. If we look at random writes however, the Summit’s 64MB of on-board cache obviously make a difference as it can outperform the every drive, including the Intel, in tests past 128K data size. If we look again at reads, this time sequentially, no drive can compete with the Intel solution though the OCZ Summit is grouped with the Apex and even VelociRaptor RAID 0 array. Back at writes, only the pair of WD VelociRaptors can beat the Summit drive from OCZ.
