The PlayStation 5 comes with an 825 GB of onboard solid-state storage. But not all of is actually accessible for users to download games and media onto their consoles. As far as usable space goes, the PS5 only offers 667.2 GB of it.
The reason for the massive space gap is because there are things like the operating system, firmware, and updates that Sony wants to make sure every PlayStation 5 always has room for. Even with that in mind, 158 GB is certainly a sizable chunk of the PS5’s default storage to make inaccessible. Then again, it isn’t that much different from either of the next-gen Xbox models. The Xbox Series X has 1 TB of storage with only 802 GB of usable space, while the Xbox Series S comes with 512 GB of storage, with only 364 GB available to use.
While 667 GB isn’t a small amount of space, it will be consumed quickly with ballooning game install sizes for next-generation games. For example, Call of Duty: Black Ops Cold War with Call of Duty: Warzone installed could take up as much as 200 GB on PS5.
Unfortunately, one thing players can’t do is install and play their PS5 games on an external hard drive, as they could on PS4.
The good news for players who are hurting for space is that at some point in the future, Sony will allow players to install an NVMe SSD to expand the PS5’s internal storage. While Sony hasn’t revealed the compatibility details just yet, we know that players should be able to use any drive that meets Sony’s specification requirements and install it in the console.
As of launch, PlayStation 5 players will be limited to the system’s default 667 GB of storage, but that should be enough to take care of many of the initial games that people will be playing — although if you want to install a few PS4 games to the SSD as well, you’re going to run out of space faster.
