In the age of computers it is essential to know about the variousaccessories that are used in a computer. Pen drive is one suchaccessory which has made the carrying and transfer of files from onemachine to another very easy and fast. In a `pen` you can literallycarry your entire office.Pen drive is integrated with USB (Universal Serial Bus) interface. Itis a NAND (which stands for `Not and`) type of flash memory technologythat excels at reading, writing and erasing data from flash memory.Their size ranges from 1 inch to 4 inches or 2.5 cm to 10 cm. They aremuch smaller than floppy discs and weighs less than 2 oz. The storage capacity of a general pen drive ranges between 64 MB to64GB. While they show a steady increase in storage and price pergigabyte, some pen drives have a capacity of one million re-writes orerase cycles with a ten year data retention capacity when connected toUSB 1.1 or USB 2.0.The major advantages of USB pen drives over other portable storagedevices such as floppy discs or DVD/CD is their compact shape and size,they operate faster and can hold more data. As the pen drives are notassociated with any moving parts, they operate more reliably. In recent times, the more updated computers lack floppy disc driveswhile USB ports appear in every current mainstream PCs and Laptops.Most of the pen drives use the USB mass storage system which can besupported by any modern Operating System such as Windows, Mac OSX,Linux and other Unix oriented systems. Pen drives using USB portsfunction faster than the optical disk drives. The pen drive contains a minute circuit board which is protected byplastic, rubberized or metal case. Such sturdy protection shields thepen drive while being carried in the pocket or key chain. The USBconnector is shielded by a removable cap or it can be automaticallyretracted into the body of the drive. This prevents it from beingdamaged even when exposed. Most of the normal pen drives use standard A - USB connection. Thesestorage units combine a number of older technologies with low cost, lowpower consumption and small size possible now by the recentadvancements in micro processor technology. The memory storage is basedon earlier EPROM and EEPROM technologies. Hardware designers later developed pen drives which carried their ownmicro processor system. These are the miniaturized version. This formof miniaturization was facilitated by the development of high speedserial data interface. In computers using pen drive, the controllersystem has full control over the stored information bank. However, the actual EEPROM writing and erasing procedures are stillquite similar to the earlier mode of operation. The fastest pen drivecurrently available use dual channel controller. The over all filetransfer speed varies considerably and are measured in megabytes ormegabits per second. The essential components of a pen drive are maletype USB connector, USB mass storage controller, NAND flash memory chipand crystal oscillator controlling the device`s data output. Additional components are test pins and jumpers, LED`s to indicate datatransfer, write protecting switches, unpopulated space, USB connectorcap or a cover and a transport aid. The USB pen drives have beenintegrated into other commonly carried items such as watches, pens andcan even be fitted into novelty toy cars. Their small size and affordable price makes these drives increasinglypopular peripherals. Pen drives are primarily used for data transfer,secure data storage in application and software files. They areparticularly popular among system and network administrators and alsoenjoy notable success in PC repair field as a means to transfer datarecovery and anti-virus software.
