That's why I suggested GNU ddrescue -
it auto-adjusts the block size for best throughput.
(... I think. These days I mostly just use cp foo.iso /dev/sdb.)

And that's the thing.. all I want to do is "cp file /mnt/blah" too.

And that method (cp) does report the highest throughput -- it's just that it caps out at 27 mbyte/sec. Whereas on a Windows laptop or workstation, it smashes it out at 75mbyte/sec. (And there are plenty of reviews online confirming the high speed)

I guess it's just something in the Linux usb implementation sucking in some peculiar way to this Corsair stick.. :(
