RAID - Redundant Array of Inexpensive Disks Redundancy (or mirroring) means that the data you write to the hard drives is stored with a backup so that if you suffer the loss of one drive in the array, you can reconstruct all of your data from the remaining drives. Array means more than one drive working together and appearing to your machine as one storage device Inexpensive related originally the difference in price between a group of 3 to 10 small hard drives and the expense of a single gigantic drive used in servers. This distinction is largely academic now. Disks usually mean hard drives, but can be other media. One intrepid soul made a RAID out of five USB floppy drives. The RAID function is controlled either by software or by a dedicated RAID controller card. Generally, a hardware RAID controller is faster but more expensive. Software RAID relies on your machine's CPU to do the calculations, so can slow perfomance down somewhat. There are two components of a RAID array; striping and redundancy (or mirroring). Striping takes your data and divides the bytes across two or more hard drives. The theory is that the writing and reading speed will be faster because as drive A is dealing with one byte, drive B is already getting a head start finding the next byte to read or write. This improves oveall speed because transferring the data takes only 20% of the time needed, the other 80% of the time the drive needs to move the heads and wait for the data on the disk to rotate around to the head. The simplest RAIDs are called RAID 0 (striping) and RAID 1 (mirroring) RAID 0 simply uses two identical hard drives, and stripes the data between them to create a single volume. There is no redundancy, therefore if one drive has a failure, ALL the data is lost on both drives. Cheapest but risky. 2 x 100 Gb drives in RAID 0 = 200 Gb space RAID 1 (Mirroring) just means two drives, where data is written simultaneously to both. Drive B is a mirror of drive A. This provides good redunancy, at the expense of half or the drive space. 2 x 100 Gb in RAID 1 = 100 Mb space. RAID 2 through RAID 5 are various
arrangements of 3 or more drives, where data is striped across the drives,
but "parity" data
is also stored, to be able to reconstruct any single drive. Typically
one drive is consumed
by the parity data, so You can also combine RAIDs, such as a striped pair (RAID 0) mirrored
by another identical striped pair (RAID 1), which is sometimes called
RAID10 or RAID 1+0 or RAID 0+1
Because there is no redundancy, and you are combining the risk of two drive mechanisms failing, RAID 0 is risky unless you maintain a fulltime backup onto another drive. RAID 1 - 5 provide additional security but have significant costs for drives, controller cards, and drive enclosures. Remember that RAID 1 - 5 only protect against drive failure. If you delete a file, have a crash or get a virus, the damage is done instantaneously to the mirror as well as the primary data, so RAID gives you no protection against those events.
