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 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.
In our first test we see the Plextor M3 Pro taking advantage of the increased write speed, now up to 350MB/s in our tests. The read speed reached an impressive 540MB/s, just 10MB/s shy of SandForce's compressible data read speed. The Plextor M3 Pro doesn't distinguish between compressible and incompressible data, though.
