Why format SSD?

An SSD stands for "Solid State Drive". It’s a type of disk which stores mediums in the computer. Compared with traditional hard disk, it has many advantages. Like a hard disk, an SSD must be divided into one or more partitions to store data. Thus, formatting an SSD also means formatting SSD partition.

As SSD becomes more and more common, formatting or reformatting becomes important as well. For example, a computer may run slowly after being used for a long time. A lot of useless programs, accumulative viruses, corrupt files and so on can all be problems. You may need a clean installation of Windows, Then, a proper SSD formatting is a good choice, which will clean the SSD so that you can get rid of a virus, your computer can run faster or you can upgrade system.

Here are three effective methods introduced to help you format an SSD.

With Windows built-in tools, system partition and boot partition are not allowed to be formatted. You will find the option “Format” is greyed out when right click C drive.
