Real file transfer test among eSATA, Firewire400 and USB 2.0

Today I have tested file transfer rate of my external hdd, WD My Book Home Edition 1TB, via all 3 interfaces.

First with eSATA, the transfer rate went up to 66 MB/s.

Secondly by Firewire 400, it can do around 31 MB/s.

At last, through USB 2.0, only 29 MB/s can be reached.

Umm, and where is 3Gb/s specification! -- Just kidding.
