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.
This last year OCZ started measuring their baseline performance in ATTO with a queue depth of 10. This is started to spread across the industry, but we're still using QD4. Because of this our maximum read and write speeds are a little different than OCZs, but still very close. In the write test we reached just over 400MB/s in several of the block sizes. The read test was very close to the claimed 550MB/s, our max was 546MB/s.
