EXTERNAL DRIVES
A number of vendors are now making external hard drives. These often connect to the
computer through the USB port, but can also connect through the network (and be shared
by other users) or other connections. While some are intended for expansion, many are
marketed for the purpose of “mirroring” data on the internal drive(s) and often incorporate
a push-button switch that starts a backup.
