I once had (after a fall of about 1m) a 'data-Gau' which could not be remedied even by professionals. That really annoyed me and I decided only USB flash drives still have to buy with rubber coating. The stick is going well thanks USB3 (much. Not the all-fastest) and the processing is solid. The experiment with water I have not dared - but I'm sure the Stick 'swim' can also. Had a 16GB stick long and never had any problems in use.
