When connected to the iMac, the R6’s AJA System Test read scores came in at 566MBps—6.8 times faster than the DS4600 using FireWire 800. Even more impressive was the R6’s 644MBps AJA System Test write score, which is 11.5 times faster than the FireWire 800 scores of the DS4600.

There was little question that Thunderbolt would handily beat FireWire 800, but now you can see just how wide the gap is.
