Question |
With all of the
virtues of RAID 5 and RAID 6 storage systems, when
would one ever employ RAID 1? |
Answer |
There are several
situations where a RAID 1 configuration is very
appropriate. When there are only two drives in a
storage system, RAID 1 (also know as disk mirroring)
is the only RAID level that can provide data
protection if a drive fails. And, since a RAID 1
configuration can be constructed with just two
drives, it generally offers the least expensive way
to protect one’s data from a drive failure.
Though RAID 1 configurations are the least efficient
with total storage capacity (reserving 50% of the
total capacity for data protection), it can
sometimes offer greater performance than either RAID
5 or RAID 6 configurations. This is frequently true
after a RAID 5 or 6 system is degraded by a drive
failure. |
