Flash drive
USB is not a flash drive. A flash drive is so called because it uses flash memory that retains data with no power.
Flash memory works by storing information on a flash drive. This can be done by connecting the flash drive to your computer or laptop, and then transferring the information over to the drive.
Dragging it to the flash memory usually means copying it to a memory which is slower and can be portable.The desktop memory however is faster than flash memory but sadly not portable.
A flash memory card is a card that holds digital data. An example of a flash memory card would be an SD Card, Micro SD, Memory Stick Pro Duo, Flash Drive (Thumb Drive, USB key). All Ipod models except the ipod classic use flash memory. Flash memory has no moving parts, but, hardrives do. Those are classified under, non-flash memory. Flash memory cards have different memory capacities. The higher the capacity, the more expensive it will be. But, the higher capacity, the more stuff can be put on it. Hope this helps

You can write to a flash drive and read data from the flash drive. It acts the same as a miniature hard drive, just like the one on your computer. It uses flash memory, hence the name flash drive.
