RAID 0 (Stripe)
Data is split into blocks over two or more drives at same time for high speed and large capacity.
Capacity
Data Safety
Performance
RAID 1 (Mirror)
Data is written at same time to two drives only for highest level of data safety and redundancy.
Capacity
Data Safety
Performance
RAID 10 (1+0)
Data is Striped (RAID 0) over two Mirrored sets (RAID 1) of drives for fast redundancy.
Capacity
Data Safety
Performance
RAID 5 (Stripe with Parity)
Data is Striped (RAID 0) while incorporating parity over three or more drives for the best combination of speed, capacity, and redundancy.

JBOD
(Just a Bunch Of Disks/Drives)
Each disk shows up as an individual logical volume on the computer. A 4 bay unit populated with drives will have 4 logical drives show up on the computer.

Span (N-RAID)
Combines capacity of two or more drives of varying size without any RAID data distribution scheme into one logical desktop volume.
