Known by a variety of names including thumb drives and flash drives, these are digital storage devices which are designed to be easily transported.
Introduced in 1998 they are currently available in various capacities up to 256 GB however it is anticipated that eventually 2 TB USB thumb drives will be introduced.
They are frequently inserted and removed from USB ports; this can put strain on the connectors and joints within the USB thumb drive. The most common cause of failure for a USB thumb drive is a dry joint, which is where the solder joints become brittle and break so that the user can no longer access the stored data. USB thumb drives can also be easily snapped when they are attached to a computer.
