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.
Transcend's marketing documents rate the SSD320 at 560MB/s read and 530MB/s write speeds. In our testing with ATTO we recorded the read speed at just under 558MB/s and the write speed at just over 533MB/s. With newer drivers, I suspect we'd be able to achieve the 560MB/s sequential speed.
