Questions about this item

What does the 100MB/s transfer rate mean when copying large files to my computer?

It means you can move a 1GB video file in roughly ten seconds under typical USB 3.0 conditions, though actual speed depends on the host controller and file mix.

How does the USB 3.0 interface limit performance compared to newer standards?

The drive caps at 100MB/s because USB 3.0 tops out around 5Gbps; it will not reach the higher throughput of USB 3.1 or USB 3.2 ports.

Will the black casing fit side-by-side with other devices in a crowded USB hub?

The slim rectangular body is designed to sit flush in standard Type-A ports without blocking adjacent slots.
