The Thermaltake BlacX 5G is an amazing external transfer solution. I was impressed with the early USB 3.0 results at CES and I am even more impressed with them now. The transfer speeds and real world tests were almost dead on with internal and eSATA speeds. They, by far, trumped the aging USB 2.0 tests with no prejudice. If you look at the real time transfer tests, which is what this dock is all about (transferring files), the slowest time it took to transfer a 1GB file was 10.8 seconds on the 3.5 inch hard drive. The USB 2.0 version of the Thermaltake BlacX and the EZ-Dock with a USB 2.0 connection both took over 27 seconds for the same file to the same drive.
