flash drive:
Standard-A USB plug – provides a physical interface to

the host computer.
USB mass storage controller – a small microcontroller with a small amount of on-chip ROM and RAM.
NAND flash memory chip(s) – stores data (NAND flash is typically also used in digital cameras).
Crystal oscillator – produces the device's main 12 MHz clock signal and controls the device's data output through a phase-locked loop.
Cover – typically made of plastic or metal, protecting the electronics against mechanical stress and even possible short circuits.

commonly carried items, such as watches, pens, and even

the Swiss Army Knife; others have been fitted with novelty cases such as toy cars or LEGO bricks. Particularly in the Far East bizarre USB flash drives with images of dragons, cats or aliens are very popular. The small size, robustness and cheapness of USB flash drives make them an increasingly popular peripheral for case modding.
Some flash drives are expensive because they have 1TB storage capacities; others are extremely pricey because they're mushroom-shaped gadgets covered in diamonds and other precious stones. Swiss jewelry maker recently launched luxury Magic Mushroom USB flash drives that can only store up to 32GB of data, but could cost almost $37,000 depending on color of diamonds
