Re: More questions
1) It is extremelly easy to install any operating systems out there. As long at You don't try Gentoo, you're good to go. Scale is 0. Too easy.
2)You can RAID multiple drives. As to my knowledge goes, you can RAID 4 drives as one. How that gets proceeded is that you need two drives, being the IDENTICAL model.If you don't, RAID utility won't allow you that.
In order to set RAID, you choose two drives of the same model and add them. For RAID 0, 1, 5 or 10 configuration, that is a little more techie, but stillvery easy.
RAID 0 is the most performent in speedwise, but the less secure. RAID 10, being the most secure and is actually faster than RAID 5. But be warned: When one drive fails, you lose ALL of your DATA...BOTH DRIVES WILL HAVE YOUR DATA LOST!
