information.
To create a RAID 5 disk volume, a
minimum of 3 hard drives are required.
The storage capacity of a RAID 5 array
is equal to (N-1) * (size of smallest
hard drive). N is the number of hard
drives in the array.
RAID 6 Disk Volume
The data are striped across all the
hard drives in a RAID 6 array. RAID 6
differs from RAID 5 that a second set
of parity information is stored across
the member drives in the array. It
tolerates failure of two hard drives.
To create a RAID 6 disk volume, a
minimum of 4 hard drives are required.
The storage capacity of a RAID 6 array
is equal to (N-2) * (size of smallest
hard drive). N is the number of hard
drives in the array.
RAID 10 Disk Volum e
RAID 10 combines four or more disks in
a way that protects data against loss
of non-adjacent disks. It provides
security by mirroring all data on a
secondary set of disks while using
striping across each set of disks to
speed up data transfers.
RAID 10 requires an even number of
hard drives (minimum 4 hard drives).
The storage capacity of RAID 10 disk
volume is equal to (size of the smallest
capacity disk in the array) * N/2. N is
the number of hard drives in the
volume.
