I have a P4P800-e deluxe, and I would like to add a 500-750 gig hard\ndrive. I have two Seagate SATA drives in a mirror array on the Intel\ncontroller, and an IDE hard drive and DVD drive on the IDE\ncontroller. I do not have anything on the Promise controller. Can I\nadd a single SATA drive to the Promise controller? If so, I would\nprobably remove the IDE drive. From what I've read, it seems like the\nlarger SATA drives are more reliable than the IDE drives. Thanks for\nany help.
