The best defence against losing precious data is to back up your important files regularly. There are a number of ways to do this, but one of the most popular is to store your data on a USB flash drive.
A flash drive combines a flash memory data storage device and a USB interface.
USB flash drives allow you to easily copy and transfer data from your computer. The data can then be stored on the USB drive and reinstalled on your computer if your computer suffers an event that causes you to lose data.
Though USB flash drives are small, usually less than 4 inches in length and weigh less than an ounce. But they can be easily carried in your pocket, or even attached to a key chain or other personal belongings.
A typical USB drive costs $20 to $250 and has a capacity from 2GB up to 64GB. For this reason, the drives are most suitable personal and small business people with a relatively small amount of data to back up. Large businesses would be better served by other means of storage.
