Regardless:
RAID = Redundant Array of Independent/Inexpensive Disks. Basically the use of multiple storage disks for purposes such as fault tolerance, increased uptime, and mirroring. Commonly you'll see RAID levels like RAID 1, which is mirroring, and requires at least two disks. Mirroring means that whenever data gets written to one drive in the array, it is also written to the second drive. Thus if one drive goes south (or is removed), the other one will take over.
PATA = Parallel ATA - the older, now legacy hard drive interface. It has the wider 40 pin (or 80 pin) connectors. You are probably familiar with SATA, which is Serial ATA and uses serial electrical signals.
