What are the RAID levels?
RAID 0 (striping): This will “stripe” two or more hard drives together and treat them as one large volume. For example, two 250GB drives will RAID 0 to a single 500GB volume. Ten 250GB drives would show up on the desktop as a single volume with 2.5 terabytes of storage. Advantage: Because a little of the data written is kept on each drive, performance of the stripe increases the more disks are added to it. Writing to 10 drives is roughly 10 times faster than writing to 1 drive. This is especially handy if you need large and fast volumes. Disadvantage: Every drive has a limited life and each disk added adds another point of failure to the RAID. Every disk in a RAID 0 is critcal – losing any one of them means the entire RAID (and all of the data) is lost. Despite the disadvantage, RAID 0 is used by those wanting the most performance out of two or more drives. Video/Audio editors commonly use RAID 0. RAID 1 (mirroring): RAID 1 will create an exact duplicate of a volume on the fly. Every t
