In order to fully utilize SATA III you need a system with native SATA III support. P67, Z68, Z77 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 ports 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.
When I first read about RunCore's 560MB/s claim on the read performance I was a bit weary, but as you can see here, RunCore pulled it off. We even managed to get a little higher in our testing, but not a full megabytes worth. The claimed write speed of 530MB/s was a little off, but not by much.
