A couple issues.
Always recommend doing a check on any flashes.
f3-9.0-1 is a tool that checks for fake usbs. Have gotten some that
show a bigger size, but are generally much smaller, and fail in real
use.

These tools can run some test to make sure you have a good usb.
The f3fix, can be used to resize a fake usb to its real size, but I
would generally just scrap them. One had a 2TB flash that tested to
just under 64G.
A second thing, I've been getting m2 usb external cases. Have one
with a 2TB nvme, and others with 1TB and 500G. So not sure on
speed differences or support.
I've been maintainer of Free G4L disk imaging project since 2004.
Like to do Disk images that can restore a system if a disk crashes.
But it doesn't take a longer time, since it backs up everything
(clearing unused sectors will greatly reduce image size, but not
time).
Final thing, I use rsync to copy specific directories to other
partitions or devices, and also to other machines as backup. These
are smaller, and faster than disk or partition images.
Just for some options.
Good Luck.
I already have f3, and have used it. I like it. It has found 1 or 2
bad sticks.
The problem I had was almost certainly not a bad stick.
I'm not familiar with m2 usb external cases and nvme. I'll have to
research those. It will take time.
Thank-you, Mike.
