diskette: A thin, flexible diskette in a protective jacket that stores
magnetically encoded information. Diskettes can be removed from
the computer and come in two sizes: 5.25-inch and 3.5-inch. The
server uses 3.5-inch diskettes.
disk mirroring: A technique in which the contents of a hard disk are
duplicated on other hard disk(s) to protect against data loss. Any
changes made to the contents of the original disk are simultaneously
applied to the other disk(s).
disk striping: The spreading of data over multiple hard disks to improve
performance. The technique combines a set of partitions (which
must all be the same size) residing on separate disks into a single
volume that the operating system treats as a logical drive. All the
partitions can be accessed at once, greatly increasing data
throughput. Disk striping does not inherently provide fault tolerance
or error checking. It is used in conjunction with other techniques,
such as disk mirroring.
