PS4’s Mandatory Installs Won’t Eat Up Your Hard Drive – It’s Just Cache Space

Those worried about needing a bigger hard drive after it was revealed that Call of Duty: Ghosts would need 50GB of space on the hard drive, and Knack would need 37GB shouldn’t worry – while it needs that space, it won’t take it up, simply caching the install instead.

That means as you play, it will install and delete data, saving you a lengthy install time and valuable hard drive space. Essentially then, you’ll have at least 400GB of space on your hard drive to do what you want with.


This makes a lot of sense, actually – it’s a smart way for the PS4 to do things, and the box sleeves saying that X space is required are still true – it doesn’t say anywhere that it will use up that space.

So, we can all breathe a sigh of relief now, and try to ride out November while we wait for the PS4 to arrive.

Another interesting tidbit of information is that the PS Camera isn’t actually required for voice commands – you’ll be able to shout into your mic attached to the DualShock 4 instead.

UPDATE: This has been confirmed in the official PS4 FAQ.

When playing disc-based games on PS4, do I need to install data to the hard drive?

Yes, all PS4 Blu-ray Disc games must be cached to the hard drive to ensure a smooth gaming experience. However, certain titles may not require you to wait for the game data to be fully cached before starting gameplay. In order to start playing disc-based games, users will need to insert the game disc into PS4 just like on the PS3 system.


  1. Thank goodness for that. Can’t wait to get my PS4 next year!

  2. Cool

  3. The dual shock 4 has a mic on it?

    • Yup, It has a mic and a speak on top just below the touchpad. Played with the Playroom last weekend here in the UK and the system worked really well, the speakers on the controller are a bit like the ones on the Nintendo Wii controllers but better quality.

      • I knew about the speakers but not the mic. Pretty cool.

  4. Doesn’t that mean it’ll be regularly reading from the disc drive though? I’d rather it fully install and save on wearing out the drive.

    • Don’t most games unless you download a digital copy?

      • On 360 when a games installed it only reads the disc when it loads up.

      • On PS3 games without an install yes, but most games don’t dump 50GB of data every time you play them.

        360 just spins the disc to verify ownership, then runs off the HDD

    • It depends on when the cache is ‘cleared’ if it’s when you put another bluray in the drive then if you’re playing a game for a few days or weeks then the cache probably won’t clear, or it may be that the game loads frequently used assets into cache as the game loads.

  5. Finally some good news!

  6. How is this a good thing?

    Caching 50GB constantly to and from the HD/BR is going to trash both of them surely?

    • Reading or writing does not contribute to harddrive wear & tear. Its more like like to be seeking (i.e. the arm moving) which causes it. So whether reading or writing wear and tear is determined by usage.

      Compared how a desktop OS uses disks it should be a lot less.

    • When your PC is on it’s constantly (just about) reading/writing from/to the HDD and they last for donkeys of years, unless your unlucky.

  7. As people have already said, I’m not sure this is actually a good thing. Can see hardware failure rates being pretty high using this approach.
    Hopefully with these new consoles we are given the choice to either install the game entirely to the HDD or use this cache method.

  8. cool news about the voice commands using the DS4. Thats nifty actually.

  9. Jesus Christ that’s awful

    Going to be fucking your BD drive & HDD transferring that much data every single time you insert a disc

    Very worrying!

    • According to GAF it was a miscommunication. It’s basically a background installation that works like the feature where you can play the game after downloading only the first part of it.
      @yosp tweeted the following:

      “you can pick which game data to delete, you want to keep the data on HDD while you play the game often”

      This sounds like it’s basically the same as PS3 game data except that it’s the whole disc. This time around you can delete it without having to fear for waiting times in case you suddenly want to play a game again since it’s a background process but it’s not a good idea to do this every time between gaming sessions for obvious HDD / BD strain.

      • That’s a relief then, from this article it sounded like a nightmare.

  10. Good to have it conformed finally, I thought this was the case but there seemed to be a lot of confusion around the issue.
