guarding
A type of data redundancy that uses a set of physical drives to store data and a single, additional drive to store parity data. Using guarding, the
user's data is protected from the loss of a single drive. Guarding is sometimes preferred over mirroring because it is more cost effective in
systems with a very high storage capacity. However, guarded configurations are significantly slower for applications that frequently write to the
array, because each attempt to write to the array requires multiple read and write commands to maintain the parity information. If this is a problem,
mirroring or duplexing is a better choice. See also
mirroring , RAID 4 , and RAID 5 .
