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

The good and the bad
TheGood and The Bad


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.


  • 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.
