i am in need of a backup drive of 1 tb or 2 tb and it typically takes 8-10 hours to backup my files (lots of photos). i was interested in esata connection drives since it seems that it is much faster than sata with a usb connection... my computer is a dell xps 730 and about 2 months old running vista ultimate 64 bit o/s... so the questions are: how much faster is an external esata drive compared to a usb connected externa drive? is there a particular drive that you would recommend? do i need to add hardware to my computer before i connect the drive (new card?)? will vista have any problem recognizing the drive or do i need to do something special once the drive is connected? any other concerns about esata drives?
