Following up next is our usual ATTO read and write tests. ATTO is an often quoted benchmark, because it is easy to use and accurate. For the most part, it is a favorite among reviewers, and I've grown to embrace it as much as the next for the last little while. ATTO uses easily compressible data, so SandForce based SSDs will perform very well here; Indilinx Everest based drives such as the OCZ Agility 4 256GB and Vertex 4 256GB -- well, here are our results. As manufacturer peak read and write performance ratings are usually done in ATTO, whether a drive lives up to its marketing claims or not can be validated by this program. OCZ claims the Agility 4 256GB's maximum read is 420MB/s, whereas its maximum write is pinned at 410MB/s. According to our tests, these figures seem to be spot on. It peaked at 422.7MB/s read and 410.8/s write in the curves demonstrated in our charts above. It is not exactly considered earth-shattering quick for a SATA 6Gb/s drive, but do keep in mind this is a mainstream product.
