In this article I will give you full information about the Hard Disk.
What is the hard drive?Hard Drive - Hard Disk or HDD is the same thing, it's a physical disk that we use to store all kind of data like videos, images, documents etc in our computer.
The difference between hard disk and RAM is that the hard disk is the thing which comes for data storing purpose, but RAM comes in handy to run the things stored in that storage.
When we turn off the computer, any thing that is found in the RAM gets cleared. But in HDD the computer does not erase when the computer closes.
Why does Hard Disk Slow happen?
Whenever we store the data on the Hard Disk, it is stored in pieces, and many times those pieces go into different parts of the Hard Disk. When there is a lot of data then in our hard disk, our computer has a little difficulty in finding things in the hard disk, due to which it gets slows down.
If you have to keep the hard disk fast, then from time to time, you should continue defragmenting hard disk with your computer's software. By defragment, all the pieces of files continue to come together instead of being at different places, and our computer does not have any problems in finding files on the hard disk.
