We understand that Digidesign doesn't officially support RAID drives. But the reason that the Glyph RAID drives work with Pro Tools is because they are hardware RAID products, and they show up to the computer as a single drive. Pro Tools can't tell that they are a RAID. It is true that Pro Tools will NOT work on software RAID drives (using Disk Utility on the Mac or some other utility to stripe or mirror drives). We have done extensive testing with all of our RAID products and are sure they work well with Pro Tools.
