How about a RAID guide?

[Soul Rider]

With more and more people venturing into the RAID arena, how about we get a guide written providing as much information as possible about RAID and how it works?

If people want to submit questions that would be useful in a guide, then either people can supply the answers, or they can be researched on the net, to provide a comprehensive list of information.

Put you Q&A below and we will try and get something up here for people to refer to..

That covers the basic, what is RAID question.

I think we might also need to look at the benefits of each type, For example

RAID1 - Provides redundancy in the event of disk failure but no performance enhancements. Works out expensive as you have to pay for the disk space required twice (1 for storage, 1 for mirror image).

RAID0 - Provides no redundancy (therefore isn't really RAID), offers improvements to read and write speed (Maximum increase of 100% - 2 drives, 200% - 3 drives, 300% - 4 drives.

Any other ideas?
