How do I find my internal hard drive on my Mac?

Locating the internal hard drive on your Mac is easy to do once you know where to look. The hard drive contains all of your files, applications, and operating system, so it’s important to understand how to access it. In this comprehensive guide, we’ll walk through the steps to find your internal hard drive on any Mac computer.

What is an Internal Hard Drive?

An internal hard drive is a data storage device located inside your computer. It is sometimes referred to as a hard disk or HDD. The hard drive is where all of your digital content is stored, including:

  • Documents
  • Music
  • Photos
  • Videos
  • Applications
  • Operating system files

Hard drives come in different storage capacities. Some common sizes for internal hard drives are:

  • 250 GB
  • 500 GB
  • 1 TB
  • 2 TB

When you first purchase your Mac, it will come with an internal hard drive already installed. However, you can always upgrade to a larger capacity drive if needed. The hard drive allows your Mac to store data permanently, even when the computer is powered off.

Reasons to Upgrade or Replace Your Hard Drive

There are a few common reasons you may want to upgrade or replace the internal hard drive on your Mac:
