RAID Levels

RAID levels explained

Below is a table showing the different RAID levels

RAID	Capacity	Large Data Transfers	High I/O Rate	Data Availability
Single Disk	Fixed 100%	Good	Good	Single drive MTBF
RAID 0	Excellent 100%	Very Good	Very Good	Poor * MTBF of drive
RAID 1	Moderate 50%	Good	Good	Good
RAID 3	Good - Very Good*	Very Good	Good	Good
RAID 5	Good - Very Good*	Good - Very Good*	Good	Good
RAID 6	Moderate - Good~	Very Good~	Good	Very Good
RAID 0+1	Moderate 50%	Good	Very Good	Good
RAID 1+0	Moderate 50%	Very Good	Very Good	Very Good
RAID 30	Good - Very Good*	Very Good	Excellent	Excellent
RAID 50	Good - Very Good*	Good - Very Good*	Excellent	Excellent

* dependant on the number of drives in the RAID (3 to 16).

~ dependant on the number of drives in the RAID (5 to 42).
