Digidesign has performed preliminary tests using Firewire drives with Pro Tools. Although Firewire drives are not yet officially supported by Digidesign, Digi has enough confidence in the performance ability of the latest Firewire bridge technology, the Oxford 911 chipset, to inform Pro Tools customers that Firewire drives are an option when used with the guidelines listed below. Because Digidesign is not able to officially support Firewire drives at this time, it is recommended that you review the compatibility documents provided by the Firewire Drive manufacturer to make sure the drive meets the guidelines listed below.
