We understand that Digidesign doesn't officially support RAID drives. But the reason that our RAID products work with Pro Tools is because they use hardware RAID, 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 another utility to stripe or mirror drives). We have done extensive testing with our RAID products and we are sure they work well with Pro Tools.
