Most current USB mass storage devices use the bulk-only protocol. The protocol requires each SCSI command to complete before the host can issue the next command.
UASP, or USB Attached SCSI Protocol is more efficient because it allows multiple, concurrent commands.
The UASP specification is available here:

The USB Attached SCSI (UAS) transport protocol specification is available here:
