Questions about this item

Does the box include the cable I need to connect the USB 3.0 micro B port to my computer?

Yes, the package contains the portable SSD and a USB 3.0 cable, so you can plug it in straight away without buying anything extra.

The specs list only a 2TB capacity — is that the only size available for this WDBAYN0020BBK-WESN model?

This specific model number is the 2TB version; other capacities carry different model numbers, so choose this one if you need 2TB of storage.

What does the 400MB/s read speed actually mean when I copy files to my laptop?

The 400MB/s figure is the maximum sequential read speed, so large files such as videos or backups will transfer noticeably faster than on a mechanical drive, though real-world speeds vary with file size and system.
