IMO, do not use IDE raid unless it's software RAID, and then shy away from
it. RAID 0 and 1 are probably reliable on both 3ware cards and software RAID,
but RAID 5 is definately dodgy on both - I have read so many nightmare stories
about such setups that if you're going to do RAID 5 then only use hardware
SCSI controllers (Mylex for example). These are pricey, but they will not kill
you data with gay abandon - cheap (or not so) IDE RAID cards can afford you
false security.
Just my 2p.
