Rugged Flash Drives: 5 Fast Facts

Fact #1. Flash memory is a non-volatile, solid-state form of transistor-based computer storage. It has no moving parts, unlike traditional hard disk drives. Information contained within it is stored even when the memory chip has an uncharged state. Data on flash memory chips is erased and rewritten electronically.
Fact #2. A Japanese engineer invented flash memory while working at Toshiba in the 1980s. At the time, the only electrically erasable programmable read-only memory erased data very slowly. This made it impractical. The speed at which the inventor's newly developed memory could function prompted a colleague of his to suggest the name flash. He felt it operated as quickly as the flash of a camera.
Fact #3. The memory inside of a rugged flash drive is no different than the memory found in any other USB drive. It's what surrounds the memory that makes the difference. In order to be considered rugged, the USB device must, at a bare minimum, be shock, dust, and water-resistant. Some companies take this a step further and manufacture fully waterproof drives. To increase the drive's resistance, manufacturers will coat them with some form of rubber silicone or aluminum.
Fact #4. Many rugged flash drives can withstand extreme temperatures and pressure. This means you can take one along on nearly any expedition. You can dive in frigid waters or hike across desert trails with no adverse effect on the flash drive or the information it contains.
Fact #5. Many of these flash drives offer some form of data security. It's usually software capable of automatic encryption. This form of encryption allows you to create a password that users must input to access data on the drive. Some even feature a data self-destruct feature that will automatically destroy your sensitive data if the device is brute-force hacked.
