Questions about this item

What does the 40 Gbps rating mean when I plug this cable into my laptop and drive?

The cable supports up to 40 Gbps on USB4 Gen3 or Thunderbolt 4 ports; on USB 3.2 Gen2 ports it caps at 20 Gbps. Real-world reads reach 2.8 GB/s and writes 2.1 GB/s with compatible hardware.

Which interface standard limits the speed and power I actually get?

USB4 Gen3 and Thunderbolt 4 allow the full 40 Gbps and 240 W; USB 3.2 Gen2 limits bandwidth to 20 Gbps and may restrict charging below 240 W.

What physical clearance do I need for the connectors on each end?

Each end uses a standard USB-C plug; allow enough depth for the connector body plus strain relief so the cable sits without bending sharply at the port.
