A computer flash drive is a small, portable flash memory card that plugs into a computer’s USB port and functions as a portable hard drive. Computer flash drives are touted as being easy-to-use as they are small enough to be carried in a pocket and can plug into any computer with a USB drive.
Solid state drives are data storage devices that use solid-state memory to store persistent data with the intention of providing access in the same manner of a traditional hard disk drive.
