Description

ON

SPAN: Spanning concatenates multiple hard drives

into a single large disk. Provides no performance or

redundancy benefits.

OFF

ON

RAID 0 (Stripe): Striping combines multiple disk into

a single large disk array. The data is split evenly across

each disk simultaneously. Read/write performance

is increased as a result, but failure of any one disk will

make the entire array unusable.

OFF

ON

RAID 1 (Mirror): Mirroring writes the same data across

multiple disk, creating a mirror copy. This provides

redundancy in case one drive fails.

OFF

ON

RAID 3: Uses striping to write data to multiple disks

like RAID 0, but reserves one disk for parity. The single

parity disk is a bottle-neck for writing since every write

requires updating the parity data. Failure of any one

disk will still allow access to the data, until the disk is

replaced.

OFF

ON

RAID 5: Uses striping to write data to multiple disks

simultaneously and distribute parity across multiple

disks. Failure of any one disk will still allow access to the

data, until the disk is replaced.

OFF

ON

RAID 01 (0+1): Creates a mirrored array, then stripes

each mirrored disk. Combines the performance of RAID

0 with the redundancy of RAID 1.

OFF
