AS SSD Results
AS SSD is a benchmark that uses non-compressible and completely random data. What this means is that the drives using the SF-2281 controller cannot compress the data first, which takes away one of the strong advantages of this controller. Therefore this is a useful benchmark because drives that use the SF-2281 don't gain an upper hand.
The OCZ Vertex 4 got off to a promising start, posting very competitive sequential read speed and the highest sequential write speed we’ve ever recorded. 4k read and write speeds were very competitive as were its copy speeds.
On the most important test of 4K read/writes speeds with 64 threads, which best simulates more strenuous usage with a lot of data being queued, the Vertex 4 stormed ahead with speeds that were easily 30% - 50% ahead of its next closest competitor. Without the advantage of compressible data, the Indilinx Everest 2 controller on the Vertex 4 certainly had the upper hand in this benchmark.
