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 with native SATA III when possible.
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.
The Intel 520 Series 240GB drive manages to read compressible data at just over 556MB/s. When writing the same drive achieves just over 526MB/s. The results are a little higher than Intel's claimed performance and in line with several of the newer SF-2281 controlled drives we've tested in the last few months.
