The computer you use for connecting to the MX or connecting to scsi drives external to the MX can have any type of drive. I have a XP machine at present as my main MX interface and that is fitted with a SATA SSD, I also have other XP machines with normal SATA, I have a windows 2000 machine with an IDE drive, and even a windows 98. My windows 10 laptop also works.
