Our benchmarks measure the performance of the hard drive in sequential read and write tests to give an overall measure of maximum performance. The key figure, though, is the AS SSD 4K 64 thread test. This simulates lots of small files handles simultaneously – which is exactly what happens in normal desktop apps that slow your PC down. The OCZ drive here is the one to beat, while the Kingston V+ has a few characteristics that have dogged SSDs since they first appeared.
