Older computers with USB 1.0 ports cannot take
advantage of the tremendously higher speeds of the new ports. If you have room for
another PCI card in your machine, you can add USB 2.0 ports to your system.
FireWire Drives
These portable drives use a different interface (IEEE 1394) than the USB drives do, but are
otherwise similar. The interface is popular with portable music players and digital
cameras. Most of these drives were created for the Macintosh platform, but the Linux
kernel supports them.
CD-RW and Recordable DVD
For newer computers that have some kind of built-in recordable CD or DVD drive, it??™s hard
to debate other choices for your backup. CD-R disks hold 700MB of data and cost less than
a dollar; CD-RW (Read-Write) disks are only a little more for the same amount of space.
CDs are durable, compact, and provide a mountable file system. This makes them more
versatile than tape for restoring files. They are less fragile than Zip drives and use a more
mature technology than the keychain drives. Transfer speeds vary depending on the
drive, but all are acceptable.
