As I mentioned earlier, the data transfer test is a very simple one. Take a file that weighs in at 1.75GB and start moving it around like crazy. While this test does not take into consideration things such as CPU utilization or access times, it does give us a firm number so we can judge how much time this device actually takes to move data from one place to another.
Once again we see the e.SATA and SATA speeds nearly identical. USB speeds are a good deal slower, but again this is the neighborhood that I expected the drive to operate in. Consider that even USB 2.0 has a maximum theoretical bandwidth of 480Mbps.
