Answer / sunilbaglur
RAID-1: 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.

Answer / pradeep kumar
Raid 1 used for mirroring .
Minimum 2 disk required in order to configure the Raid 1.
Its one of the best solution for the fault tolerance of the
failed disks.
You can remove the failed disk and add a fresh disk which
will synchronize automatically.
RAID 1 specially for mirroring the disk in order to avoid
the downtime bcoz of failure of HARD DISK.

Answer / venkatesh
RAID I, for example, writes two copies of the data
simultaneously on two separate drives. This is called fault
tolerant because if one of the mirrored drives suffers a
mechanical failure (e.g. spindle failure) or does not
respond, the remaining drive will continue to function. The
RAID 1 configuration is performed either by a hardware RAID
controller… or performed in software. It is suited to
applications requiring high fault tolerance at a low cost
and where a duplicated set of data is more secure than
using parity. RAID 1 is popular for accounting and other
financial data. It is also commonly used for small database
systems, enterprise servers, and home PCs where a fairly
inexpensive fault tolerance is required.
A RAID device maintains a mirror of all the data in a
partition... on another partition. This second partition is
usually on another drive (note: in Linux systems the second
partition can be on the same drive). There is a small
performance hit to be expected when configuring your hard
disks in a RAID 1 partition as the data has to be written
to every disk in the RAID array
