Currently USB 3.0 is a touchy subject. Most onboard USB 3.0 solutions only allow read speeds to around 200MB/s and write speeds of 180MB/s. A few PCIe aftermarket cards are delivering faster results. We use the GIGABYTE X58A-UD7's USB 3.0 port.
For the comparison we chose to add some of our previous USB 3.0 products and the fastest USB 2.0 drive we've ever tested.
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.
Using ATTO we see that the Kingston HyperX MAX 3.0 delivers read speeds of around 167MB/s and write speeds of 183MB/s.
