A closer look at the PCB of the Luxon and we can see that as well as supporting eSATA and USB 2.0 interfaces externally, it is actually also capable of supporting either an IDE or Serial ATA hard drive internally. While Serial ATA is now by far the most prevalent standard in the desktop hard disk market, if you're looking to reuse an old drive as a backup device or the like then the Luxon's capability of supporting an IDE drive may well be most welcome.
