The USB flash drives were first introduced in 1998. The popularity of USB drives has increased since then. The USB drive is actually a plug and play device used for storage purpose. USB drives use flash memory. The USB drives are so lightweight that you can even attach it to a key chain. The popular names of USB drives are the keychain and flash drives. The USB drives are alternatives to the other storage devices like the compact disk, zip drive and floppy disks. These USB drives are easily compatible as the operating system of the computer recognizes the USB drive when it is plugged into the USB port. The operating system recognizes the USB drive by assigning a removable drive letter to it. The USB drives are compatible with both computers and digital cameras. These drives are very compact. To store data, the USB drive usually uses USB 1.1 or 2.0 interface.

The USB flash drives are the form of NAND type flash memory. This type of flash memory was developed for the purpose of transferring of data information. The NAND type memory has the new and latest technology to record huge amounts of data and also has fast writing/erasing speed. USB drive is composed of small circuit board which is sealed by a secure case made of metal or rubber. The purpose of the ssecure case is to protect the inner circuit board. It also has a serial bus connector.

The new and advanced design of the USB drives help them to record more amount of data. The USB drives provide ease and convenient to its users.

The USB drives usually have 3 components. The first component is the type A male connector. This connector interfaces with the host computer system. The storage and the balance of information are done by the USB mass storage controller. The USB mass storage controller increases the process of data transfer, encryption and decoding. The USB flash drive provides the best quality of output with the help of the crystal oscillator.

The floppy disks had the problem of not being properly read by the floppy drive, and therefore, it caused problems to its users while transferring of the data. The floppy disks had many parts inside them that were movable that is why most of the time the floppy drives were not able to read the data. The USB drives have overcome this problem.Shawn Paul (Marketing Manager)http://www.tape4backup.com34972 Newark Blvd, # 501, Newark CA 94560 Tel: 888-491-4949 Fax: 888-449-5050 Email: sales@tape4backup.com
