ive been told that a raid setup will improve my computers performance,but all i know about it is that you need two identical hard drives...i currently have a 40gb ata main drive and a 120gb ata drive for storage...i have a few questions if anyone can help
1-do i need 2 identical drives to set up raid ?
2-will it work with ata drives
3-can i keep the storage drive aswell?
4-do the raid drives go on one ata cable?
5-is it worth it?

regards mark
