No.
How fast for sequential transfer will depend on the usb it is attached to.
Sequential write speed range = 3~10 MB/s
Sequential read speed range = 10~25 MB/s
USB 3.0:
Sequential write speed range = 10~35 MB/s
Sequential read speed range = 75~110 MB/s
Modern hard drives will be in the 100-200MB/s range.
Ignore the instantaneous cache to sata rates,, ultimately the mechanical limitation will be much less
If you really want speed look to a ssd.
sata will be 500MB/s, PCIE 4x will be 3500MB/s.

Depends very much on the drives in question. And keep in mind the hdd is running the OS and any other background software as well, so it has further demands on its time and dedicated drive of any type might help out.
Using a USB drive as a dedicated disk for a particularly slow to load game isn't a terrible idea.
Doesn't really apply in this case, but there are some pretty speedy 3.0/3.1 USB drives out there. They do make USB SSDs in the stick form factor (though they are quite a bit larger still) And your typical SATA SSD is far cheaper anyway.
USB 3.2 on the way, should make SSD to portable drive transfers a breeze and won't require expensive drives.
