hey. i have a raid card coming with my new mac that I am waiting on (2-3 weeks). i just wanted to make sure that what I am wanting to do with my system is right as I have never used RAID before. so I'm an audio guy who was going to have a Raptor program drive, two 1TB SATA-300 drives in RAID 1 (internal) for audio-projects, and two 320GB SATA-300 in RAID 0 for samples (in an external dual bay). my question is if the raid card will utilize my four SATA drives and work with my external dual-bay drives. I am confused as to if I can only utilize my card for internal drives. someone also suggested that the card was only for SAS drives. and what is this about iPass that i keep hearing about???? I was thinking that a raid card is just there to optimize the RAID config...not sure if you have to have the drives connected to it or what... it would be upsetting if I can't do external SATA drives, and if this is the case and would change my order. please reassure me!
