Why Does My PS4 Only Have 400 GB of Storage?

The frustrating reality is that your PlayStation 4 (PS4), even if advertised as having a 500GB hard drive, doesn’t provide you with the full 500GB of usable space. The reason is simple: a significant portion of that storage is reserved for the system software (OS), which is essential for the PS4 to function. This is standard practice across virtually all devices with storage, from computers to smartphones, and is necessary for the operating system to exist and run the device. This operating system consumes a pre-defined amount of hard drive space for system files and updates. While the PS4 boasts a 500 GB drive, after deducting the OS requirements, you’re typically left with around 407 GB of usable space.

Understanding the Storage Allocation

The allocation of storage space is a critical design element for any device. Let’s break down where that “missing” storage goes:

  • Operating System (OS): The largest chunk of reserved storage goes towards the PS4’s operating system. This includes the core software, system applications, and necessary files for the console to run smoothly.
  • System Updates: Space is also reserved for future system updates. Sony regularly releases updates to improve the PS4’s functionality, add new features, and enhance security. These updates require storage space for installation and temporary storage.
  • Pre-Installed Applications: Some applications may be pre-installed on the PS4, such as the PlayStation Store, media players, and other system utilities. These applications consume additional storage space.
  • File System Overhead: A portion of the storage space is used for the file system itself, which organizes and manages the data on the hard drive. This overhead is necessary for the PS4 to read and write data efficiently.

Managing Your PS4 Storage Space

With less than the advertised 500GB available, managing your PS4 storage becomes crucial. Here are some strategies to keep your storage under control:

  • Delete Unused Games: Games are the biggest storage hogs. Regularly uninstall games you no longer play to free up valuable space. Don’t worry; your game saves are typically stored separately, so you won’t lose your progress.
  • Remove Unnecessary Media: Videos and screenshots can quickly accumulate and consume significant storage space. Delete any unwanted media files to reclaim storage.
  • Back Up Saves: Utilize PlayStation Plus’s cloud storage or a USB drive to back up your game saves. This allows you to delete games without fear of losing your progress.
  • Archive Games: Consider archiving games you don’t play frequently but want to keep. Archiving moves the game data to an external storage device, freeing up space on your PS4’s internal hard drive.

Expanding Your PS4 Storage

If you consistently run out of storage space, consider expanding your PS4’s storage capacity:

  • External Hard Drive: The easiest way to expand your storage is by using an external hard drive. PS4 supports USB external hard drives, allowing you to install games and applications directly onto the external drive.
  • Internal Hard Drive Upgrade: You can replace the PS4’s internal hard drive with a larger capacity drive. This requires a bit more technical expertise, but it’s a viable option for those comfortable with hardware modifications. Upgrading to a solid-state drive (SSD) also reduces game load times.

Frequently Asked Questions (FAQs)

1. How much storage does a 1TB PS4 actually have?

A 1TB PS4 will typically offer around 861 GB of usable storage after accounting for the operating system and system files.

2. Can I add more storage to my PS4?

Yes, you can add more storage to your PS4 using an external hard drive connected via USB or by replacing the internal hard drive with a larger capacity drive.

3. Is 500GB enough for a PS4?

Whether 500GB is enough depends on your gaming habits. If you only play a few games at a time, it may suffice. However, if you have a large game library or frequently download new games, you’ll likely need more storage. Expect to store around 10-12 larger games on a 500GB drive.

4. Is 1TB a lot for a PS4?

1TB is a significant improvement over 500GB and can comfortably hold a larger game library. Most gamers find 1TB to be sufficient for their needs.

5. Is 2TB overkill for a PS4?

Whether 2TB is overkill depends on your usage. If you have an extensive game collection and plan to download many games, 2TB can be beneficial. Otherwise, it might be more storage than you need. The Seagate 2TB External Game Drive for PlayStation 4 allows gamers to have all the extra space needed.

6. Does low storage slow down PS4?

Yes, low storage can negatively impact PS4 performance. When your hard drive is nearly full, the system has less space to manage files and data, leading to slower loading times and potential performance issues.

7. How do I upgrade my PS4 storage without losing data?

To upgrade your PS4 storage without losing data:

  1. Back up your data to an external hard drive or USB drive.
  2. Download the latest PS4 system update to a USB drive.
  3. Replace the internal hard drive with the new one.
  4. Reinstall the system software using the USB drive.
  5. Restore your data from the backup.

8. How do I get more space on my PS4 without deleting games?

You can get more space on your PS4 without deleting games by using an external hard drive or upgrading the internal hard drive.

9. Does deleting games free up space?

Yes, deleting games frees up space. When you uninstall a game, the game files are removed from your hard drive, reclaiming the storage space they occupied.

10. Will I lose my games if I delete all saved PS4 data?

No, deleting a game doesn’t delete your saved game data. Saved data is stored separately and can be managed in the “Application Saved Data Management” settings.

11. What happens when PS4 storage is full?

When your PS4 storage is full, you won’t be able to install new games, download updates, or save new game data. This can significantly limit your gaming experience.

12. How do I update system storage on PS4?

You update system storage on PS4 by either replacing the internal hard drive or adding an external hard drive.

13. Will I lose data if I rebuild PS4 database?

No, rebuilding the PS4 database will not erase your games, saves, or other personal data. It reorganizes the data on the hard drive, potentially improving performance.

14. What is the highest TB for PS4?

While technically you could use an 8TB external hard drive, the sweet spot for most PS4 users is generally between 2TB and 4TB, balancing cost and capacity.

15. Why doesn’t my new external hard drive show the full storage advertised?

This is a very common issue with new external drives. Usually, the drive itself is fine. The difference is due to how manufacturers and your computer calculate storage. Manufacturers use a decimal system (1TB = 1,000,000,000,000 bytes), while operating systems often use a binary system (1TB = 1,099,511,627,776 bytes). This difference in calculation results in the displayed storage being less than advertised. It does not mean you have a faulty drive.


Gaming and consoles are constantly evolving, and it’s interesting to see how these technologies are being implemented in learning and education.
