What’s the Size of PS4 Hard Drive?

The size of PS4 hard drive is not something that pleases most users due to its limitation. Its size is small enough to fill with just less than 10 games (assuming each game is 50gb+). Even if you own PS4 Pro or PS4 Slim, the bigger hard drive size doesn’t still satisfy the needs of an average enthusiast. In fact, this small size is only one bad aspects of the PS4 stock hard drive in general. We always strongly recommend to upgrade PS4 internal hard drive in order to enjoy bigger size and higher performance.

Measuring PS4 Hard Drive Size

So, what’s the size of PS4 HDD? Well, before answering this question you have to know that any hard drive size is measured by two scales: The actual storage capacity, and the available storage space.

As for the actual size of PS4 hard drive, it’s 500gb. You can find that written on its cover once you pull it out. (see image below)

The actual size of PS4 hard drive

But you won’t be able to fully use that size due to several technical reasons. One of these reasons are that PS4 system preserves part of that size for caching and storing the system files. So, what usable size you’ll get out of PS4 hard drive? Well, you’ll get around 407gb of usable storage capacity. (see image below)

Now, in order to maintain the peak performance of PS4 HDD and avoid any potential failure, you have to keep at least 5% of that size FREE and empty. That means you have to cut off around 20gb from this calculation. Therefore, almost 387gb remains for you to install your games and apps and store other data like movies and screenshots.

PS4 Pro and PS4 Slim comes with 1tb hard drive size

Ok, that’s about the initial version of PS4. Later after 3 years of its release, Sony started to ship PS4 with 1tb hard drive. That’s the same hard drive size that PS4 Pro and PS4 Slim has.

Calculating the New PS4 HDD Size

So, as said above, if you own the new PS4, PS4 Pro, or PS4 Slim, you’ll get 1tb hard drive size. Again, you won’t be able to fully use that storage space, as the usable storage space is less.

How much storage capacity remains for you to use? Well, let’s see the image below.

So, here we go..

You’ll get, as you can see, 861gb of available storage capacity. You have to keep minimum 5% of that size free, and that means almost 43gb. So, what remains for you in fact is 818gb of usable space.

That amount of hard drive size can barely hold 15 games, which doesn’t seem enough for a wide variety of users.

Expanding PS4 HDD Size

There are some major benefits from expanding/increasing the size of PS4 hard drive, that are:

  • Getting more rooms for additional games and movies. This is a clear advantage of increase PS4 hard drive size to at least 2tb.
  • There’s no need to add an external hard drive. To a variety of users, adding an external hard drive to PS4 is another headache. By replacing the internal hard drive of PS4 and increasing its size, you’ll get rid of that problem.
  • More flexibility for multiple users. If your PS4 is shared by others, say family member, then increasing PS4 hard drive size makes sharing more flexible and easy.

That’s it. In all cases, it is good to have a larger size hard drive for PS4.

How to increase PS4 HDD size

There are two fundamental ways to increase PS4 hard drive size:

  1. Either replace the internal hard drive of PS4 with a larger drive, or
  2. Add an external hard drive as an extended storage

Both methods have their own advantages and disadvantages, and to learn more on that in detail, please visit our article: Best 5 methods to expand PS4 Hard Drive Storage.


It’s true that PS4 hard drive size is too limited to meet the modern storage standards of today’s gaming. What can 500gb or even 1tb do today with tremendously huge games that can easily occupy almost 100gb of storage space? Think about it seriously if you want more than just storage size for PS4, and the performance of your game console is one of your major concerns.

If you’re looking for a larger hard drive size than 2tb, know then that you can increase it to up to 16tb as has been already stated in our article: Largest hard drive for PS4.

After all, PS4 hard drive is not limits in size only, but also in almost all aspects, whether it is speed, performance or reliability, and must be replaced by every serious gamer.

    I know it needs to be a 2.5″/9.5mm drive, but is there a maximum as far as what the PS4 will recognize? (ie. 4TB, etc?)

    • PlayStation Expert says:

      There is only 500GB of space on the standard PS4 and PS4 Slim and a larger 1TB on the PS4 Pro. It’ll only take a few big games on base hardware to completely fill up your hard drive.

    What is the smallest amount of storage that a PS4 original can have as an internal hard drive?
    I just need some explanation because I’m seeing 160GB or 200GB:)

    • PlayStation Expert says:

      The basic PS4 and PS4 Slim only have 500GB of storage, whereas the PS4 Pro has a greater 1TB. It won’t take many large games to entirely occupy your hard disk on low-end hardware.

      With the old version of the PS4 system software, the minimum size is 160GB. I am not sure now, with version 9+ what is the minimum size required. To be on the safe tract, get at least 250GB.
