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.
Corsair Neutron 240GB on the left, Neutron GTX 240GB on the right
With all of the formalities out of the way let's gets down to business with what you really want to see. The Neutron base model with Micron 25nm synchronous flash offers an impressive 556MB/s read speed in ATTO and just under 375MB/s write speed. As you can see in the ATTO run screenshot, performance really kicks in at 4K for both reads and writes.
The Neutron GTX 240GB model has a little higher read speed at 558MB/s, but it is able to write data much faster at 513MB/s with its Toshiba 24nm Toggle Model flash.
