something strange but cool has happened this evening. i'm working in Windows 7 Boot Camp on my Mac Pro. i'm working on a project, and for my own peace of mind and security, i'm backing up my project folder from an internal hard drive (WD Caviar Black 2TB 64MB Cache) to an external hard drive (2.5" Toshiba 5400RPM USB 2.0) about every half an hour. all i'm doing is dragging over a roughly 2.8GB folder from the internal hard drive to the external USB 2.0 drive. at first the transfer speed was about 50MB/second, and then after a few hours i noticed that the transfer speeds where in excess of 120MB/second....and now i'm seeing 200+MB/second!!! the 2.8GB file is being transferred over to the external hard drive in in what seems like 5-7 seconds!! i've never seen these kind of speeds transferring data to an external USB 2.0 hard drive. how is this possible?
