RAID 4
Data striped in
blocks across multi-
ple drives. Dedicated
parity drive
High sustained data
transfer rate. No
performance deg-
radation after drive
failure.
Redundancy.
Lower performance
with small, random
requests
Performance- driven,
single or multi-
threaded applica-
tions
RAID 5
Disk striping with
distributed parity
High read perfor-
mance, medium
write performance
with data protection
in
Usable storage
capacity equals total
capacity of all drives
in the array less the
Content creation
applications requir-
ing data protection
performance
RAID 6
Block-level striping
with double
distributed parity.
Double parity
provides fault
tolerance up to
two failed drives
Usable storage
capacity equals total
capaciy of all drives
in the array less
the capacity of two
drives
File and
Application servers,
Database servers
RAID 10
Built from two or
more equal-sized
RAID 1 arrays
Mirroring
provides data
protection, and
striping improves
performance
Usable storage
space is 50% of
total available
capacity
Content Backup
and Content
creation
applications with
data protection
