4.3. RAID Configuration
The dual NVMe SSD slots support various RAID modes (RAID 0, RAID 1, JBOD) to optimize storage performance or data redundancy. RAID configuration is performed via Disk Utility on your Mac. For detailed instructions, please refer to the tutorial video below.
Video 4.1: Tutorial on setting up RAID mode for the ACASIS M001Pro dock. This video demonstrates how to configure your NVMe SSDs for Striped (RAID 0), Mirrored (RAID 1), or Concatenated (JBOD) modes using Disk Utility on macOS.
Note: RAID 0 mode can achieve speeds up to 40Gbps (2869MB/s read/write) with two identical M.2 SSDs. Other modes offer up to 1594MB/s. The theoretical running speed of a single M.2 disk is 20Gbps.
