A USB flash drive, which is also commonly known as a pen drive, is a small device that is used to store data or transfer it from one computer to another. Although some of these may be very small in size, but they can store huge amounts of data, making these an extremely useful computer accessory. Storing a flash drive is also not a problem as you can carry it as a key chain.
Besides being extremely handy, a USB flash drive is also easy to use. Simply plug in the drive into the USB port of your computer and wait for a short while as the software installs itself on to the machine. Once the process is complete, you can simply copy and paste the data, which you want to store or move, from your computer hard disk on to the flash drive.
It is extremely important to keep a backup of all your important work so that in case of an unfortunate event such as a hard-disk crash, the damage can be limited. That is where the usage of a pen drive comes in as it offers an easy, convenient and affordable means of storing your important data for later use. Moreover, the data on the drive can be overwritten several times. So, the user can easily delete any unimportant data and replace it with other information of use.
A USB flash drive also comes in handy at school or office when you want to transfer some of the data from the workplace to the home, especially when there is no provision of internet. Another highly significant reason for using a USB flash drive is that it is more reliable than a floppy disk and has a life span much more than a floppy when subject to the same amount of abuse.
