The days are quickly counting down for this test system as I'm finished validating the new X79 rig. We're not finding a lot of differences between P67, Z68 and X79 when it comes to SATA III products, but the X79 sure does look good. In your own system the only way to get the full performance of SATA III is to use one of these systems with native SATA III onboard.
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 ATTO we see solid SATA II performance of 283MB/s read and close to 260MB/s write speeds. The 4K performance is right around 191MB/s write and 160MB/s read speeds. To me the biggest competitor to this new series of products is the older SandForce SF-1200 drives, but their 4K performance was right around 173MB/s write and 130MB/s read (numbers taken from the Corsair Force 40GB) so the new drives have a big performance lead in that area.
