How Much Hard Drive Space Do I Need?

4438398_f520 Learn how to determine how much hard drive space you need with DataTech Labs.

As technology advances, hard drives will continue to grow in size and complexity. Similarly, how much hard drive space we need will also evolve.

Now that there is such a large range of options, it can be very hard to know how much hard drive space you need. Simply put, you should choose which size hard drive is right for you depending on your lifestyle and computing needs.

Below, I have listed a few steps that may help you decide how much hard drive space is needed for your next computer.


Knowing some of the terminology can be very important. Do you know the difference between a bit and a byte? Knowing the difference can help you approach your purchase with confidence.

A bit is the smallest unit of information in a computer. A bit is represented by either zero or one. This sequence of zeros and ones is called binary code. A binary code represents computer processor instructions using the numbers 0 and 1. A binary code assigns a bit string to each symbol or instruction.

When it comes to bytes, eight bits equals one byte. Each byte can represent a character such as a number or letter of the alphabet. For example, it takes one byte to represent the letter “A” which is made up of eight bits 01000001. Some more terminology is explained below:

Kilobyte = 1,000 bytes or 8,000 bits
Megabyte = 1,000 kilobytes or 100,000 bytes or 800,000 bits
Gigabyte = 1,000 megabytes or 100,000 kilobytes or 100,000,000 bytes or 800,000,000 bits
Terabyte = 1,000 gigabytes or 100,000 megabytes or 100,000,000 kilobytes or 100,000,000,000 bytes or 800,000,000,000 bits


A good way to gauge how much hard drive space you will need on your new computer is to check the space you have used on your current computer.
You can check this by going to your “Start” menu and selecting “Computer” and right-clicking on your hard drive. A graph will appear and show you how much hard drive space you have used thus far on your current computer. Identify your greatest memory users. Here are a few things to remember when thinking about how much memory you use and on what:

  • A large-resolution photo can take up to 5-20MB, but a smaller photo can take up only 200KB
  • A 2-hour move can take up to 2GB of space at HD quality and upwards of 10GB with 4K definition and higher
  • An average-length song will take up to 5MB of hard drive space
  • An advanced video game can take upward of 100GB of storage


If you believe you will use the same amount of space on your new computer, then you probably have the right size, but if you would like to increase the space on your hard drive, you will want to decide by how much.

If your new computer will have new features like a TV tuner that records your favorite shows, keep this in mind as you calculate your future hard drive space needs. Also, remember that computer applications require space and if you want to add new ones, you will need to keep that in mind as well. Even if you do not plan on doing anything too different, it is safe to say you should probably upgrade your drive to a higher amount of space just to be safe because remember that your current hard drive will probably be transferred to your new computer and this will take up a lot of space.

Whether you’re a professional, a student, a creative enthusiast, or a dedicated gamer, your digital world revolves around the capacity of your hard drive.
