Several years ago companies started releasing USB pen drives which have reinvented the way stored data could be transported. USB pen drives (and other flash products, such as memory cards used in your digital camera) use NAND non-volatile flash memory, which is able to store and retain data even without power, making this type of memory very versatile. Pen drives were expensive at first release but now you can pick up a 1GB drive for just a few dollars, and flash memory prices are constantly decreasing. Not too long ago, some smart chap had the idea of replacing the aging hard disk drive bound with problems such as heat, size, weight, noise and mechanical failure with solid state technology. Instead of using a hard drive with moving parts, why not create a new type of drive, which is solid state and more reliable, using flash memory chips?
