What is a flash drive

What is a Flash Drive

  • A USB flash drive is a NAND-type flash memory data storage device integrated with a USB interface. They are typically small, lightweight, removable and rewritable.

  • USB Flash Drives are sold with memory sizes anywhere from 32 Megabytes to 60 gigabytes.


Basic history

Basic History

  • The first flash drives were created in 1998 by Dov Moran. Dov’s most significant contribution was that the flash drive was self-reliant and free of the need to install drivers. The first flash drives were produced by M-Systems and were in Europe.

  • Modern flash drives now have USB 2.0 connectivity.

  • The sizes of an 8 MB, 16 MB, 32 MB, and 64 MB. and this design was continued up to 256 MB. Asian manufacturers soon started making their own flash drives that were cheaper than the M-Systems series. The fastest drives available now use a dual channel controller.


How does it work

How Does It Work?

  • Flash Drives (for the most part) are only active when connected to a computer USB port or USB hub. Flash drives have no battery or internal power source and are only powered by their connection to the computer.

  • Modern Operating Systems support USB Flash drives without the need to download a driver from disk or the web.


Essential components

Essential Components

There are typically three parts to a flash drive…

  • A Male type-A USB flash drives provides an interface to the host computer.

  • NAND flash memory chip stores data.

  • Crystal oscillator produces the device's main 12 MHz clock signal and controls the flash data output through a phase locked loop.

Common uses

Common Uses

  • Personal Data Transport: Such as music or this slide show.

  • Arcade Games: When a new machine is brought in or if a machine needs maintenance the high scores are stored on a flash drive.

  • Flash drive are used by network administrators for loading new software and configurations for troubleshooting and maintenance.


The good and the bad

TheGood and The Bad

Good:

Flash Drives are more convenient then some older forms of portable memory, Namely Floppy Disk. They Are…

  • More compact

  • Contain More Memory

  • Faster

  • And More reliable

  • Modern Operating Systems come with the ability to talk to USB drives without having to download an additional drive from the web or CD-Rom.

    Bad:

  • They are still breakable.

  • If something goes wrong with the Drive there’s no way to fix it because there’s no software on it and no anti-virus devices.

  • Like any form of flash memory they can only have a certain number of transactions before it fails.
