As Hard Disk contains all files of Operating System of computer, so Hard Disk is also one of the important parts of computer system. Instead of storing operating system, the main use of hard disk is data storage. Small sized files like word files, images want less space on disk whereas movies, songs, videos want more space. In that case 80 GB or 160 GB hard disk looks small for our data. But now rapidly upgrading technology introduced TB HDD i.e. Tera Byte hard disks.
1 TB hard disk is equal to 1024 GB. That means near about seven to ten times greater than 80 or 160 GB hard disk. But price of 1 TB hard disk is not seven to ten times greater than price of 80 or 160 GB hard disks. Here the price is near about half times greater. So TB hard disks are rapidly getting popular. Such hard disks are really very useful for small scale servers, large data storage etc.
