RAID10 (RAID1+0: striping + mirroring)

• A combination of RAID1 and RAID0 — mirroring and striping, but without
parity.
• RAID10 is used for both replicating and sharing data among disks.
• RAID10 is often the primary choice for high-load databases, because the
lack of parity to calculate gives it faster write speeds.
• RAID10 volume capacity = 2 x (capacity of smallest HDD)

Characteristics/Advantages
RAID0
RAID0 implements a striped
disk array, the data is broken
down into blocks and each
block is written to a separate
disk drive
I/O performance is greatly
improved by spreading the I/O
load across many channels and
drives
Best performance is achieved
when data is striped across

Disadvantages
Not a "True" RAID because it is
NOT fault-tolerant
The failure of just one drive
will result in all data in an
array being lost
Should never be used in
mission-critical
environments
