What is RAID 1 ?

Answer Posted / san saroj

This type is also known as disk mirroring and consists of
at least two drives that duplicate the storage of data.
There is no striping. Read performance is improved since
either disk can be read at the same time. Write performance
is the same as for single disk storage. RAID-1 provides the
best performance and the best fault-tolerance in a multi-
user system.
