It makes a lot of sense for backing up a home system, but less so for backing up all computers on a home network.brianko wrote:But not the fastest...a USB-2.0 compliant external drive will do about 480 Mbps, about 4x as fast as a network drive running on a 100Mbit network. For a home network, a USB-based storage device probably makes more sense.
A USB drive attaches to computer, not a network. That computer must always be up and running, and must have all the permissions properly set, for other computers on the network to access the drive.
