Operating Instructions

RAID Configurations

This 40Gbps dual-bay enclosure supports software RAID configurations. Please configure the RAID on your PC or Mac using Disk Utility or similar software.

• RAID 0 (Striped): Combines two drives for increased speed (up to 2x 8TB, fast 40Gbps speed). For optimal performance, use identical drives.
• RAID 1 (Mirrored): Creates an exact copy of data on both drives for data protection (smallest drive capacity).
• JBOD (Concatenated): Combines multiple disks into one large volume, capacity is combined (macOS only).

Note: Data will be deleted when setting or changing the RAID array. Always back up your data first.

Dual Monitor Display

Expand your workspace with dual monitor support. The enclosure features 1 HDMI port and 2 USB-C 40Gbps ports for display output.

• Single-screen use: Up to 8K@60Hz resolution.
• Dual-screen use: Up to 4K@60Hz resolution per screen.

Please note that computers with M1, M2, or M3 chips can only output to a single display.

Troubleshooting

Frequently Asked Questions (FAQ)

• Q1: Does it require an external power supply to operate?
  A1: Yes, the TBU405ProMax requires an external power supply. Since this product requires sufficient power for your device, it must be used with a power supply.
• Q2: Why won't my computer recognize anything plugged into USB?
  A2: 1. Please check whether you connect the power supply to the TBU405ProMax. 2. Please check whether you use the original Thunderbolt 4 cable. 3. Please check whether you connect it to your device's Thunderbolt 3/4 or USB4 port.
• Q3: Can two hard drives work independently in the hard drive enclosure?
  A3: Yes! Two hard drives can work independently in the hard drive enclosure.
• Q4: Why is my speed slow?
  A4: Non-RAID 0 mode supports up to 20Gbps. RAID 0 mode supports 40Gbps – use two identical NVMe drives for best performance. In Windows, go to Disk Management, right-click the disk, select Properties > Policies, and enable write caching for better performance. Daisy-chaining will reduce M.2 drive speeds.
