So I have an early 2008 Mac Pro Octo. I purchased the system with the Apple Raid card when there were few other options. I have some questions.. 1. is it possible to add the eSATA connector I have seen on OWC to connect some eSATA drives? do you connect this to the 2nd ODD spot? 2. if this doesnt work with the apple raid card, can i do it with a 3rd party card? and i would my current array be affected with installing a new raid card. i am running raid 5 config. 3. if i wanted to updrade the size of my hard drives (i currently have 1tb drives x 3) and a 250hdd for vmware stuff, do i have to back everything up on a separate drive and then transfer everything back to the new raid array?
