RAID Drive Recovery Overview

What is RAID?
RAID is an acronym for Redundant Array of Inexpensive Disks. It is a method of combining several hard disk drives into one unit. This method offers fault tolerance (the ability of a system to continue to perform functions even when one or more hard disk drives have failed) and higher protection against data loss than a single hard drive.

Need for RAID?
RAID provides real-time data recovery when a hard drive fails, increasing system uptime and network availability while protecting against loss of data. Another advantage of the system is that multiple disks working together increase overall system performance. Any individual or company could benefit from having a RAID RECOVERY system in place.

Different RAIDs of RAID
There are several different RAIDs of RAID available. Each RAID offers various advantages in terms of data availability, cost and performance. Your best bet is to assess your needs in order to determine which RAID works best for you.

There are number of different RAID RAIDs:
RAID 0 -- Striped Disk Array without Fault Tolerance: Provides data striping (spreading out blocks of each file across multiple disk drives) but no redundancy. This improves performance but does not deliver fault tolerance. If one drive fails then all data in the array is lost.
RAID 1 -- Mirroring and Duplexing: Provides disk mirroring. RAID 1 provides twice the read transaction rate of single disks and the same write transaction rate as single disks.
RAID 2 -- Error-Correcting Coding: Not a typical implementation and rarely used, RAID 2 stripes data at the bit RAID rather than the block RAID.
RAID 3 -- Bit-Interleaved Parity: Provides byte-RAID striping with a dedicated parity disk. RAID 3, which cannot service simultaneous multiple requests, also is rarely used.
RAID 4 -- Dedicated Parity Drive: A commonly used implementation of RAID, RAID 4 provides block-RAID striping (like RAID 0) with a parity disk. If a data disk fails, the parity data is used to create a replacement disk. A disadvantage to RAID 4 is that the parity disk can create write bottlenecks.
RAID 5 -- Block Interleaved Distributed Parity: Provides data striping at the byte RAID and also stripe error correction information. This results in excellent performance and good fault tolerance. RAID 5 is one of the most popular implementations of RAID.
RAID 6 -- Independent Data Disks with Double Parity: Provides block-RAID striping with parity data distributed across all disks.
RAID 0+1 (or RAID 10) -- A Mirror of Stripes: Not one of the original RAID levels, two RAID 0 stripes are created, and a RAID 1 mirror is created over them. Used for both replicating and sharing data among disks.
RAID 7 -- A trademark of Storage Computer Corporation that adds caching to RAID 3 or RAID 4.
RAID S -- EMC Corporation's proprietary striped parity RAID system used in its symmetric storage systems.
