Disk striping Offers the highest

useable storage
capacity of 100%
of total available
storage capacity
No fault tolerance -
failure of one drive

parity
High read
performance,
medium write
performance with
data protection in
case of a drive
failure.
Useable storage
capacity equals
total capacity of all
drives in the array
less the capacity of
one drive.
For example, a 4x
1TB RAID 5 yields
a useable capacity
of 3 TB.
