That doesn't mean they are the best but these are used to store and then later retrieve content. Folk that use them as a drive discover the issue you noted.

My take is that the issues are with the cheap models. http://thewirecutter.com/reviews/the-best-usb-3-0-thumb-drive/ didn't push the tests onto the cheaper sticks but went with the better models.

Conclusion? Cheap will get you storage, not "drives." If you need to use it like a drive, move to the premium models.
