Techtool Pro supports Apple Software RAID for Mirrored (RAID 1), Striped (RAID 0), and Concatenated configurations. It has also been tested with Apple’s hardware RAID card.
Techtool Pro has not been tested with other RAID types (e.g., RAID 2, RAID 1+0, RAID 50, etc.). However, if you’re using a hardware RAID that appears as a normal disk to macOS, Techtool Pro may still function correctly. As always with any disk utility, be sure to back up all your data before using the tool.
