You have probably seen or heard of USB flash drives, but what exactly are they and how do they work?
USB flash drives, also commonly called USB jump drives, are NAND-type flash memory storage devices that are integrated with a USB interface.
- USB (Universal Serial Bus): A portal that allows communication between a computer and an external device over an inexpensive cable
- Flash memory: is computer memory that can be erased and rewritten or reprogrammed
- NAND flash memory chip: stores data. NAND flash is typically also used in digital cameras.
Flash drives are very handy to use, because their small, compact size makes them easily portable. The average size is 2.75″ x .75″ x .25″ and typically weighs 2 ounces or less. Despite their small size, these storage devices are able to hold 64MB – 64GB of information, depending on the specific capacity of the device. This makes them perfect to carry your important files and information on-the-go, or to back up your files without taking up a lot of space.
Not only can you carry a large amount of data on these small jump drives, but they are also composed of flash memory. This means that they are rewritable and reusable, which is perfect for carrying around unfinished projects.
The small size and rewritable flash memory makes jump drives a great product, but there are risks. Since they are so small, it makes it very easy to lose the device and all of your important information on it. The rewritable flash memory also makes it possible to accidentally delete your data.
USB flash drives need sturdy packaging in order to help prevent damage or loss. USB drive cases could also help you keep your flash drives organized and in one place.
