Performance was tested with every possible connection combination using a SATA Drive. The entire PCB is constructed so that there is no way to break your drive or burn anything when plugging in USB 2.0, power and eSATA at once. This means that there is no need for a switch on the enclosure.
USB 2.0
The above HD-Tach results are quite respectable for the notebook hard drive enclosure. It is incredibly speedy and even beats the larger 3.5" enclosures we have tested. While the above image also shows a fairly high CPU utilization, a second run resulted in the same speed but with a mere 7% of processory usage.
ATTO confirms the above benchmarks. Once again great results!
eSATA
eSATA performance was as expected from a notebook SATA drive. The CPU utilization of 0% is a further advantage when using eSATA. The computer is tricked into thinking that a traditional, internal SATA drive is being used, resulting in the same performance.
