Regardless of the 40Gb/s theoretical limit of the bus, unless the bus can be saturated by the device, you are not running at the maximum speed of the bus.

If the bus is faster than a single device, splitting the bandwidth across multiple devices can allow for bus saturation (ie. RAID-0 configuration with drives)

You have to remember, "a chain is only as strong as it's weakest link" In this case the single SSD speed is the weakest link. To saturate 40Gb/s you would need a much faster drive than is currently available, or an array of multiple drives.
yes.. as I said.. when you have a proper usb4 portable drive.. it will be designed to read/write at speeds upto 40Gb/s or there about... samsung makes great usb3 and 3.1 drives and will be making usb4 drives as well.
