OK a word of warning on RAID setups, that I learnt to my cost. It's no substitute for an independent backup system.

RAID can protect you from an individual hard disk failure. Alternatively RAID can speed up read or write access times, by spreading the data (striping) across multiple disks. But it's also vulnerable.

If the Operating system corrupts, or there is a hardware failure, perhaps to the RAID controller, the records that determine what information is where can be lost. At that point you are in dodoo, and reliant on disk recovery software.

So by all means use RAID, to cover most day to day problems, but have a separate backup system for anything critical.
