Steady on there - we're not in the US where USPS fixed price shipping boxes have no weight limit, so people can ship lead ingots across the country for under $5. 

I did see a teardown of a purported 8 *TB* USB SSD available for suspiciously cheap on everyone's favourite online cyber-tat sites. It enumerates as 4x 2 TB USB 2 drives. Inside is a USB hub with four flash drives attached. The tearer-down couldn't be bothered to find out the actual capacity of each drive as they were so terribly slow.
