FYI.. lotta sites selling 1 or 2 TB USB sticks for peanuts, ie less than £20. Basically, they can't make them for that price. The USB controller on the stick is made to think it has 1 or 2TB of storage space. While only having (usually) 8Gb or so of actual storage.

If I could (like many PC nerds) get that kinda storage for less than £20 rather than pay £100 for a 1TB SSD.. I'd be queueing up and buying half a dozen at a time.

ie It's a scam
