5.25-inch Drive Bay
5.25-inch external drive bays can hold several different types of hardware. A CD burner, like the one
shown above, is just one example. CD-R disks can store around 700MBs, (or 700,000,000 bytes), of
information. A CD-R drive can read and write information, but it cannot erase it. A CD-RW drive can
also read and write data, but it can also erase the data and rewrite new data, which is useful if you
save something and later wish to remove it. CD-RW drives can use both CD-R disks and CD-RW disks. The
recording speed rating associated with CD-R drives varies up to 54x. It varies up to 32x for CD-RW drives.
