SuperSpeed USB 3.0 on the ASUS P7P55D-E Premium

ATTO Disk Benchmark v2.41

ATTO is one of the oldest hard drive benchmarks that is still used
today. ATTO measures transfers across a specific volume length. It
measures raw transfer rates for both reads and writes and places the
data into graphs that you can easily interpret. The test was run with
the default runs of 0.5kb through 8192kb transfer sizes with the total
length being 256mb.

USB 3.0 Performance:

Benchmark Results: On USB 2.0 we were able to reach 35MBps on the read test, which is a solid score but with SuperSpeed USB 3.0 we saw the performance jump up to 135MB/s. The write performance went from 31MB/s to 125MB/s! It is amazing what performance benefits by changing over the same drive to the USB 3.0 header gives you!
