HDD – Usable Space Closer to 400gb
The error screen had a lot going on, including an information box that revealed the current HDD space usage. If you look carefully the dev unit was using 385gb out of 423gb. When you factor in how manufacturers rate the drives you get actual usable space of 465gb. Now subtract that from what we saw on the crash screen and we get roughly 42gb of reserved system data that is not user accessible. That number could decrease or increase on actual retail systems.
What does all this mean? Well that’s simple, the actual usable HDD space on the PS4 system is a lot closer to 400gb than the 500gb HDD stat that you have seen in the past 24 hours. It’s likely that Microsoft’s Xbox One will also follow a similar path though, so this is not just Sony’s issue.
