Just a thought: I think with mac RAID is only available in the macpro line, not sure however.[/quote]



Yes, that's correct. Quite obvious since it's the only Mac that takes expansion cards.

Yes, but if we're talking about low cost RAID controllers (SATA RAID 0/1/10), especially onboard ones, then we're talking about mostly software RAID here. Lots of the work is still done by the CPU. You don't gain much compared to pure software RAID ... which of course is available on the Mac, too.

Absolutely. But note that we're talking about two very different forms of redundancy here. A RAID keeps your machine running in case of a drive failure (unless we're talking about RAID 0, which is about speed only). However, it will not protect your data in case of accidental deletion, malware activity or filesystem errors. A backup (like Time Machine) will.
