In order to fully utilize SATA III you need a system with native SATA III support. P67, Z68 and X79 systems are preferred, but AMD has made advances in their newer SATA III systems as well. Older X58 systems with Marvell based SATA III do not deliver the same high levels of performance, so we recommend newer systems when available.
ATTO Baseline Performance
Version and / or Patch Used: 2.34
ATTO is used by many disk manufacturers to determine the read and write speeds that will be presented to customers.
Using ATTO we managed to achieve a read speed over just over 510MB/s read and 442MB/s write speed. The performance is sold and in line with Corsair's claims on the specification sheet. These numbers don't really represent real world performance though but this issue isn't limited to just this product but all SSDs.
