Storage Drives

  1. Hard Disk Drives (HDD)

HDDs are storage drives that use spinning disks to save data.

They are like record players with circular disks inside, and they store a lot of information.

  1. Solid-State Drives (SSD)

SSDs are storage drives without spinning disks. Instead, they use small chips.

They are faster and more durable than HDDs.

Disks

  1. Compact Discs (CDs)

CDs are flat, round disks used for storing music, software, and other data.

They are read using a CD drive, and you might have seen them in music or video games.

  1. Digital Versatile Discs (DVDs)

DVDs are like CDs but can hold more data. They are often used for movies and large software.

DVD drives read them, and you can find them in DVD players.

Differences

The key difference is that storage drives, like HDDs and SSDs, are permanent storage devices built into computers, while disks, like CDs and DVDs, are portable and often used for specific purposes.

Drives store your operating system, programs, and files, while disks mainly store specific data, like music or videos.

Drives can read and write data, while disks are usually read-only, meaning you can’t change the data on them.

In this lesson, we learned about the difference between storage drives and disks.

Both play a role in storing data, but they serve different purposes and have various features.

We have come to the end of today’s class. I hope you enjoyed the class!

In the next class, we shall be discussing Uses and functions of storage devices.
