Sony's PS5 storage may be super fast, but looking at the install sizes of upcoming games, the 825GB SSD will likely fill up quickly.

Not much has been officially announced about the install sizes of games coming to PS5, but the install size of Demon's Souls Remake is very large at 66GB, and Spider-Man: Miles Morales Ultimate Launch Edition in full, the SSD install size would be 105GB, which would take up a large portion of the PS5's internal storage. Spider-Man: Miles Morales, the standalone expansion to the main Spider-Man game, alone would give up 50GB of SSD space.

Games are getting bigger every year; the PS4 Pro and Xbox One X have 1TB storage drives.

However, the PS5 has less storage than the PS4 Pro. Also, it is unlikely that a large game library will be installed on the launch PS5 console, unless Sony is clever about data compression when it comes to installing large games.

The PS5's storage is expandable with commercially available SSDs, but these are PCIe 4.0 SSDs and must be certified by Sony. Also, given the price of the Xbox Series X's expandable storage, such an SSD upgrade is expected to be quite expensive.

Eurogamer crunched the numbers and found that an installation of "Spider-Man: Miles Morales Ultimate Launch Edition" would take up about 13 percent of the PS5's SSD. The same goes for other games, and if a game with a huge install size like "Call of Duty: Modern Warfare Season 4" comes along, it will be bad news for the PS5's SSD space.

If you have a very fast broadband connection that allows you to download large games in a reasonable amount of time, this is not a major problem. However, if your connection speed is slow, playing next-generation games will also require a great deal of patience.

The Xbox Series X will have a 1TB SSD, which will also fill up quickly if you have large install size games.

We will know more about the SSD situation for the next generation consoles when they are released in November: the Xbox Series X will be released worldwide on November 10, and the PS5 will be released on November 12 in the US and elsewhere, but will have to wait until November 19 in the UK and Europe.

Pre-orders for the PS5 are open, as are pre-orders for the Xbox Series X and Series S, but be prepared to wait for pre-orders to be replenished, as inventory is selling out very quickly.
