Today we will be testing the A-DATA Nobility in both USB 3.0 and SATA II configurations. We are using the new Intel RST 9.6 driver for the SATA test, but have not been able to retest all of the drives shown on the list with the new driver. The A-DATA S599 SandForce SF-1200 drive was tested with the new RST 9.6 driver.
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.
USB 3.0 hasn't matured yet and the NEC bridge chip is far from offering the claimed 10x USB 2.0 performance. This is an issue we ranted about not too long ago in a review of a PCIe adapter card that uses the same NEC bridge chip that is found on the GIGABYTE X58A-UD7. GIGABYTE's USB implementation is the fastest we have seen so far, so that is what we will use for testing today.
Here we see that USB 3.0 is slower than SATA, but it is a heck of a lot faster than the 35MB/s ceiling found with USB 2.0.
