Admin's RAID Data Recovery Guide

@ 2005/04/13
Technology, how we love it until something goes wrong and we end up yelling at our computer screens. If you’ve ever lost data, you know how much time, money, and headaches it can cost you to retrieve it, especially if you are a company. Data recovery doesn’t have to be worrisome.

The acronym RAID, first used in 1988, stands for Redundant Array of Inexpensive (or Independent) Disks. RAID is an assembly of disk drives, also known as ‘disk array’, which operates as one storage unit. In general, the drives could be any storage system with random data access such as magnetic hard drives, optical storage, magnetic tapes, etc. RAID has several functions which include providing a way of accessing multiple disks grouped together to appear as a single device, spreading data access out over these disks which reduces the risk of losing data if one drive should fail, and improving access time.

not really a recovery guide per sé, more a "what are the different raid levels" article
