USB 3.0 has the performance credentials you’d expect

USB 3 SuperSpeedUpdated system interfaces are something enthusiast types get excited over because it usually means increased speeds and a whole host of new gadgetry to make use of the new ports.

USB 3.0 is shaping up to be one big increase in performance for storage and…well other devices. HardOCP has tested the standard with some mighty impressive results:

So USB 3.0 allowed us to achieve a sequential read speed about 80MBps faster than 2.0. USB 3.0 also allowed us to achieve burst speeds readings of about 150MBps faster than 2.0. Random access times are the same as this is fully dependent on the drive itself in our situation, and CPU utilization was the same as well given the margin of error.

A definite performance improvement over USB 2.0, eSATA might have lost its performance edge.
