Have been using firewire800 with my WD MyBook Studio primarily for Time Machine backup. May need to be replaced - if I replace with WD MyBook for Mac or something else ( perhaps Seagate) with usb2.0 will I notice a big change in time for TM? If I transfer files to another ext drive, will I notice longer time saving iTunes or iPhoto to an express drive??
Any comments or suggestions are welcome. I have always used WD but wonder if Seagate or someone else has something.
