Can someone explain to me what a RAID disk is/does?

I presently have a 80gig HD housing OSX etc. I also have a 200 gig HD partioned in two for archives, library etc.

Is it advantageous to create a RAID set up instead of the normal partion?
I mostly do photo work & graphics if that matters.

Any advice appreciated.

RAID is Redundant Array of Inexpensive Disks.

There are 2 basic configurations: Striping: Take 2 separate hard disks, and "join" them together - treating them as 1 big drive. This creates a disk which is very fast, but if one drive dies, you lose everything.

The other: Mirroring: 2 disks, and both contain the same data. This is like having a real-time backup drive. There isn't really any speed boost/loss.

There are other configurations, but these are the basic 2.

For photo/graphics work, you probably don't need to worry about RAID.
If you are doing video editing etc, a Striped RAID config would be beneficial, since the read/write times are faster.
So basically, RAID is how 2 or more hard disks can be/are configured on a system.

RAID is used with sets of identical disks in the ways described above. It is either used for better speed, or better redundancy. A striped (RAID 0) set will obviously be faster than a single disk. A mirrored set (RAID 1) is great if you never want to lose a single second's worth of data.

There are other fancy combinations like RAID 0+1, which, as it suggests, allows both speed and redundancy, but you'd need 4 identical drives to hold the data of two!

Hey thanks guys. I really appreciate the explanations. Seems that there's no real advantage in my situation to enable RAID. Cheers
