A hard drive is the hardware component that stores all of your digital content. Your documents, pictures, music, videos, programs, application preferences, and operating system represent digital content stored on a hard drive. It can be external or internal.
It is usually installed internally in a computer, attached directly to the disk controller of the computer’s motherboard. It contains one or more platters, housed inside of an air-sealed casing. Data is written to the platters using a magnetic head, which moves rapidly over them as they spin.
Everything stored on a hard drive is measured in terms of its file size. Documents (text) are generally very small whereas pictures are large, music is even larger, and videos are the largest. A hard drive determines the size of digital files in terms of megabytes (MB), gigabytes (GB), and terabytes (TB).
Spin speed (rotations per minute, or RPM) is relatively important. The faster a disk (platter) spins, the faster your computer can find the file you want.
A 7,200 RPM HDD is obviously faster than a 5,400 RPM. But with external drives, you’ll hardly notice a difference between the two RPM speeds. The same holds true with internal drives, especially with smaller files. However, you’ll see noticeable improvement on a 7,200 RPM HDD with larger files and applications.
If your computer’s HDD is damaged, you risk losing all of your digital content. This is why most people back up their content on an external drive in addition to their computer’s internal drive.
