EXPLANATION
RAID 1 (mirroring) – the basic idea of such a solution is the
replication (mirroring) of two or more discs. It means that while using
RAID 1, an exact copy (or mirror) is created on two or more discs. Such a
solution gives good read performance and reliability, but storage
capacity must be compartmentalized. The reason for this is that the
total storage must be equal to the capacity of the smallest disk. i.e.:
in the case of an array composed of 3 discs – 250GM, 500GB and 1TB – the
usable space will be equal to 250GB.
