[edit section] RAID

RAID Levels
Level Description Details
RAID0 Striped disk array with no fault tolerance. The several disks operate in parallel for faster data transfer rates.
RAID1 Mirroring and duplexing Creates duplicate copies of data that is split between disks. Mirroring writes from a single controller to two drives. Duplexing uses two separate controllers to write to two different hard drives. Increased access speeds.
RAID2 Data striping w/error recovery Spreads files across several disks; uses large amount of disk space as overhead to maintain parity (error checking.) Not typically used on PCs.
RAID3 Parallel transfer - parity striping Uses less hard drive space for error checking, but data transfer is more time consuming and less efficient.
RAID4 Independent data disks - shared parity disk Interleaves drives to make them appear as one large drive. There is only one parity drive that is shared. Low overhead high maintenance fault tolerance.
RAID5 Independent data disks - distributed parity blocks Popular system where parity is spread across the disks to create accuracy and redundancy.
RAID6 Similar to RAID5 Uses extra disks as well as asynchronous and cached data transmission for guaranteed fault tolerance. Could be called 'Super Raid5'.
