Adrians Rojakpot has a new guide up & running and this site is as good as one can get if it comes to guides. Here is a snip: RAID 0 shouldn't be even called RAID as it does not provide any redundancy at all. And no redundancy means no increase in data reliability and security. Even so, it is the highest performing RAID level. The hardware requirements for setting up a RAID 0 array is the least demanding of all RAID levels. It only requires a minimum of two hard disks and can use as many hard disks as the RAID controller can support. Check the RAID guide here
