2. Speed specifications explained

80 Gbps maximum interface bandwidth

The advertised connection bandwidth, not the guaranteed SSD transfer speed.

Up to 6,000 MB/s read and write

Advertised performance under suitable hardware and connection conditions.

Active cooling

The built-in fan helps manage SSD temperatures during sustained transfers.

3. Important compatibility notes

• Thunderbolt 5 or USB4 v2: Required to take advantage of the highest advertised connection bandwidth, with compatible host hardware and SSD.

• Thunderbolt 4 / USB4 v1: Compatible, but maximum speeds will be lower.

• Thunderbolt 3: Compatibility and performance can vary; some systems may connect at ordinary USB speeds.

• PCIe Gen 5 SSDs: Confirm that your unit is the upgraded TB501Pro Professional version. Earlier versions may not support these drives.

• Actual speed: Depends on the SSD, computer port, cable, operating system and workload.

• Capacity: The advertised maximum is 8TB; verify compatibility with your specific SSD.
