A rigid disk is a common type of storage device utilized in computers that comprises one or more platters made of aluminum or glass coated with a magnetic material. These are responsible for storing all your data, operating system, and program files that your computer accesses every time it starts up.
As opposed to solid state storage, hard drives are mechanical devices that feature moving parts. The disk platters spin inside the drive, but it has been a dependable data storage medium for decades. However, with the increasing demand for more reliable and quicker storage, many computer manufacturers are now offering solid state drives as an option, particularly in laptops.
Using a USB or eSATA connector, you can connect external hard drives to your computer for added storage. Large files such as media files and document files can all be stored on external hard drives.
FAQs
What is the difference between a hard disk and hard drive?
The terms are used interchangeably, but technically the hard disk refers to the physical platters used for storing data while the hard drive includes the controller board, spindle, and other mechanical components.
Why should you have an external hard drive?
External hard drives provide additional storage capacity while keeping your data on a separate device, which adds an extra layer of security. Additionally, you can move data easily between computers and backup important files.
The Bottom Line
Rigid disks have been a staple in data storage for decades, but with the introduction of high-capacity solid-state drives, their days may be numbered. External hard drives are useful for keeping your data organized and secure while also providing additional storage capacity.
