Read disturb is a different issue. pretty much all USB drives now use NOR flash Nope, NOR flash is much more expensive than NAND so NOR is only used for firmware and everything else is NAND.

But the firmware might have the logic to rewrite the block when it reads it in case it hasn't been written in a while.

SSDs should definitely rewrite static data if it has too many ECC errors. Unfortunately we don't know much about what's going on in SSDs. Some could have much better data integrity than others.
