Two things:

make a read or write call, then wait for the response, then
issue the next call. Anything describing itself as a "key"
is particularly likely to have this.
Is there any way to verify this (command wize)?
$ usb-devices
will show
Driver=usb-storage
Yep, I've got this one, a slow device.
for a slow device, and
Driver=uas
for a fast device.
Can you change your external storage?
Any suggestion?
You're looking for a device that has UASP support rather than
just USB Mass Storage. Some vendors make it easier to search
for this than others, e.g.
https://www.startech.com/HDD/Enclosures/?filter_UASP_YN=Yes
will show you all the StarTech USB3 enclosures that do UASP.
I don't have any specific recommendations.
Awsome, thanks again dsr.
