I want to purchase an external hard drive ... I would like it to have USB 2.0 and I am wondering if I should get one with the SATA plug ... and I am definitely wondering what is the best external HD while still being economical ... I have an eMac ... and I like to edit footage of my youth football team ... I have run out of space but I am not willing to delete the old stuff yet ... LOL ... anyway does anyone have any advice about what I should buy ???
