RAID for security

RAID 1 maintains a complete copy of a file set on each physical hard drive in the array. Maintaining simultaneous, complete copies of files across multiple hard drives is called mirroring. If a drive fails, the mirrored drive takes over and acts as the primary drive.

RAID 1

AA

BB

CC

File reading performance (seek time) is increased using the same methods that RAID 0 uses, although writing speed is the same as if writing to a single hard drive.

Drawback

RAID 1 treatsthe entire array as a single drive with the storage capacity of the smallest physical drive in the array. So if you have two drives (300 GB and 250 GB) in a RAID 1 array, your computer only recognizes a single drive with 250 GB total capacity.

RAID for both: performance and security

RAID 5 uses striping (at the block level) with on-the-fly error correction across all drives. Because of this error correction, small file read/write errors can be quickly and automatically fixed without a significant drop in system performance.

RAID 5 offers good performance and data redundancy. This array preserves your files if a drive fails.
