For storing information in the future, most business make use of Flash Memory Thumb Drives. With Flash Memory Thumb Drives, you can connect to a PC USB port in an attempt to back up your files on the go. While some provide data encryption in order to ensure that your data is secure should the flash memory get lost, others are not so much integrated with this security measure. They are generally rewritable, removable, and a lot smaller than the typical optical disc which makes them quite movable.
Businesses also make use of External Hard Drives. These drives can store as much information as the storage found on the computer.
