Anyone who has ever looked into their computer backup strategy in any serious way will no doubt have heard of RAID. Essentially, RAID (an acronym originally meaning Redundant Array of Inexpensive Disks) is a term used to describe an arrangement of hard drives in which numerous drives are configured to work as one. This can be done in several ways, resulting in a system which is more capable in one way or another. For example, RAID 0 (also known as striping) involves splitting information and writing on half on one drive, and half on another. This increases the performance of the drives, but increases the chance of losing data, as when one hard drive fails, the information on the other becomes useless.
For users interested in keeping reliable backups, there is RAID 1 (also known as mirroring). In this arrangement, the same information is written to two drives simultaneously, and the operating system recognises the two as a single drive. This option results in a much smaller chance of losing data, as one hard drive failing still leaves the user with the other, which contains exactly the same information. This can be an invaluable tool when it comes to backing up your computer because it is a zero-maintenance solution.
