If you have not Dell server hardware my choice of [hardware] RAID cards
would be:

LSI (or whoever owns that line these days - Intel was the last one, I

With LSI beware that they have really nasty command line client, and do

3ware after they were bought out several times by competitors were drawn
down out of existence).

Good luck!
