So I have a rather nice MDD G4. Its running 10.4 server, and does a pretty great job of housing my files. Currently it has 4x 80gb HDD's in raid, and a 40gb boot disk, I want to "kick it up a notch" and seriously upgrade the storage capacity, from about 320gb to somewhere around 4tb. I don't need the SATA card to be bootable, thats what the 40gb IDE drive is for, but I would prefer to know how much to budget before going all in for this project. Sonnet makes this SATA card that definitely will work, however I would need two. On the other hand there are a number of these Vantec and similar PC oriented cards that have enough SATA ports for my needs. So would I be able to use a PC SATA card in my MDD just to give it (non-bootable) access to SATA drives?
