Default Raid?

I don't know much about raid, well really anything, aside from the fact that everyone says it's fast. Can anyone explain what raid is and the easiest / best way to achieve it?

Yeah, you're probably going to choose between two types of RAID - 0 or 1. There's more, but you probably won't use them.

1 is Mirrored. I don't think that's what you're thinking of. It actually decreases or keeps the same performance because it basically makes identical copies of the hard drives. So when you write a file, it goes on both hard drives. This is for reliability, if one fails, then you still have all your data.

0 is Striped. A part of the data goes on each drive. So access times are decreased since each drive is accessing part of the file, as opposed to a single drive just reading the file. But on the downside, if one drive fails, you lose all the data.
