External Hard Drive

Just wondering but what is the purpose of an External storage hard drive? Is it just to backup data and protect any data needed?

SonnyNXiong, primarily an external drive is used for both storage and backup. You can use it for both. For a backup, the conventional wisdom by tech experts on backups is known as the 3-2-1 method. Basically you want:

3 copies of any data you don't want to lose
2 different mediums it's stored on (so 2 different drives in your computer, for example)
1 copy kept offsite, to prevent against disaster.

If you want it for storage of data or games it will work as well.
