The PlayStation 5 ships with 825 GB of internal storage. This is admittedly a curious amount, considering 1 TB drives are much more common. The reason for opting for a smaller drive is likely two-fold. First, a smaller drive was probably less expensive. If Sony had gone bigger, they probably would have had to pass that cost on to the consumer, increasing the console's price. There are also reports that the internal SSD is specially designed for the console. We won't get into the technical details, but the gist is that the SSD is essentially married to the PS5's CPU. This results in super-fast performance.
