									The Advantages of USB Flash Drive
A USB flash drive is a NAND type flash memory. The NAND type flash memory
was designed for the exchange and saving of data as alternative to the
magnetic disk. The NAND type flash memory has the capacity to hold large
volumes of data. The writing and erasing speed is also fast. On the other
hand the random access is rather slow because it uses block as a unit for
the purpose of writing and reading.
The USB drive is made up of secure case small circuit board and is
integrated with a universal serial bus connector. The secure case is
typically made up of rubber or metal. This secure case protects the
circuit board of the USB drive from damage and increases the robustness.
The USB drives are very much smaller than the floppy disks and are
The USB drive can be easily inserted into the USB port of the computer.
With the help of USB flash drive, data can be safely and easily
transferred. The USB drive is more reliable and safer than the floppy
disks. The USB drives are small and compact, therefore the users can
carry them easily in their pockets or they can attach it with their key
chains as well.
The USB drives are more reliable when huge amounts of data has to be
moved. Some of the USB drives allow 1 million erase or write cycles. The
USB Memory card readers have a removable flash memory card. The USB flash
drives provide more benefits to its users than the other storage devices.
Almost all the computers and laptops have the USB ports, therefore the
users can easily transfer the data. Most of the modern operating systems
have the USB mass storage standard which is required by the USB flash
drives to operate.
The USB 2.0 are much faster than the optical disk in terms of the data
storage in much smaller space. The name "drive" is given to the USB flash
drive because the USB flash appears to the OS of the computer like a
mechanical drive and the method of access is also the same.
The USB connector must be protected and kept safe using a removable cap
or by retracting the USB connector into the body of the USB flash
drive.The USB flash drives use all the power supply from the host
connection. Some high speed USB drives may require more power supply than
provided by the bus powered USB hub. Therefore these drives will function
when they are directly plugged into the self powered hub or the host
The USB drives are most often composed of three components, the male
connector type A, crystal oscillator and the USB mass storage controller.
The function of the type A connector is to interface with the system of
the host computer. While on the other hand the USB mass storage
controller helps in balancing and storage of the data. The USB mass
storage controller enhances and carries out smooth processing of the
decoding, encryption and transfer of the data between the systems. The
function of the crystal oscillator is to make sure that the out put of
the flash drive is of the best quality.
The reason that the USB drives became more popular is that the floppy
drives were most of the time failed to read the data from the floppy
disk. Therefore, the users had problems while transferring the data using
the floppy disks. The USB flash drives do not have movable parts like the
floppy disks had.
