Swapping out the hard drive in the super-slim model of PS3 (of which the 12GB is one) is a fairly simply process.
You can follow our guide for doing so here, or you can check out Sony's official instructions here.
A recent post on Rockstar's support website (via Video Gamer) informs owners of the 12GB PS3 model that they will soon need to purchase a storage upgrade if they want to be able to play Grand Theft Auto Online.
That's because, following the 1.16 patch released on August 19 (the flight school update), the system will no longer have enough space to store future updates and content, which must be installed to play GTA V's online multiplayer mode.
Although Rockstar Games is currently committed to supporting the Xbox 360 and Play Station 3 versions of Grand Theft Auto V, released in September 2013, there may come a point in the future when updates to the game are only technically possible for the Xbox One, Play Station 4, and PC editions of the game.
As part of Rockstar's latest Asked & Answered feature, a fan asked if the fact that GTA V is now available for new consoles means old-generation players will be left out in the cold.
However, like first-person mode, some future GTA V features may only be possible on the latest versions of the game, Rockstar said."We are incredibly thankful to our original generation of GTA V and GTA Online players on those systems and wish to continue providing content to them for as long as we can," the developer explained.
An update to the PS3™ system software was released on November 14, 2017.
You can use this update to upgrade your system software to version 4.82.
Being limited to the 12GB of internal flash storage won't prevent the single-player mode from being playable, but it will mean you'll be unable to take advantage of any new features or changes introduced in future updates.
It also means you'll be missing out on the single-player story DLC we know is coming, as well as the online heists that will be added. Given the size of the hard drive, you could be forgiven for thinking the 12GB PS3 was available at launch in 2006.
