Raid??

RAID 0 is for performance, it basically combines two (or more) drives into one (at least that's how the OS sees it), so you can have increased read/write speeds since data is being split between two drives.

RAID 1 is for redundancy, if you have two drives the OS only sees one. The idea here is that if one drive fails, you can use the other drive to rebuild the array so no data is lost. It is NOT a backup solution however as if you delete something, it is erased from both drives.

More then enough reading, I'm not going to try and summarize it.

If you are looking to actually understand the topic, read the full article.

But, to satiate you further....let me see if I can distill it even more from what Omega did on the most common types (Warning - Super-simplification ahead!):

Raid0 = Striping No Parity (+Speed +Risk)
Raid1 = Mirroring No Parity (~Speed --Risk)
Raid5 = Striping With Parity (+Speed -Risk)
Raid10 (or 1+0) = Mirrored Striping (+Speed --Risk)
 
If it is a decent raid controller, you also get increased read speed from raid 1, since it can read the data from more than one disk.
