Quick answer: The PS5 only has 825GB of storage most likely due to the proprietary SSD drive used for the system. It is, as this time, the fastest drive on the market and costly as a result.
The PS5 looks to offer improved performance on all fronts when compared to the PS4. Despite this, one area that seems to be oddly hamstrung is the amount of storage included.
It’s not yet known if the PS5 Digital Edition will include more storage, but as of now Sony’s messaging suggests that their next gen systems will ship with 825GB of storage.
Why does the PS5 have less storage than most PS4 models?
Based on what we know, the culprit seems to be a mixture of storage tech and Sony’s insistence on driving costs down.
