TechTool Pro supports Apple Software RAID for Mirrored (RAID 1), Striped (RAID 0), and Concatenated configurations. TechTool Pro has also been tested with Apple’s hardware RAID card.
TechTool Pro has not been tested with other RAID types (RAID 2, RAID 1+0, RAID 50, etc.). However, if you are using a hardware RAID that appears as a normal disk to the Mac OS, TechTool Pro may operate correctly. As with any disk utility, be sure that all data is backed up prior to use.
