Hey guys,
Would a USB bus-powered portable external hard drive (Like the WD Passport) be slower at backing up than an AC powered desktop external hard drive?
I've got a desktop external hard drive that I'm using for Time Machine backups over Wifi connected to an airport extreme, but it's dieing and I'd like to replace it.
Preferably I'd like to get a 1gb portable drive so I can use it for both backing up and travelling - however if it will result in slower speeds in transferring data then I'll just get a desktop drive.
