Mark Cerny explains game installation and caching on PS4

PS4 lead architect, Mark Cerny has explained just how install requirements work on the PS4.

Basically if you are playing a disc-based game, the system will begin caching the disc when you put it in the console and get ready to play. So in Knack for example you'll have to wait around 10 seconds to play the game, wit the total install taking up 37GB of space overall.

This cached/installed game data will stay on the hard drive until the user deletes it and while there have been some internal discussions at Sony about having the PS4 auto-delete installed data from games that players hadn't used in a while the hardware giant decided against it, figuring that gamers would prefer to manage space themselves.

The disc installation is required on PS4 because the console is not designed to read games off of discs as it's much faster for the system to access data straight from the HDD. This is similar to the Xbox One which works in the same way.

Cerny also explained that if a PS4 user decides to download a game, they will have to wait longer to play, although how long depends on the user's Internet connection speed. You can queue PS4 to download if you are planning to play them at a later time, so if you're downloading a game then this may be a good idea.

PS4 launches in the U.S this Friday. The European release is November 29.

Have they made it so you can use external HDs yet on this? Cus we'll use that HD space up pretty quickly.

Or a bigger and faster one.. I wonder how much of a difference an SSD would make.

Can you replace the hard drive at launch as I think I read that you can not. It could be that I just read about the external one and mixed them up.

yes you can change the HD, it is a 2.5 5400rpm not the normal 3.5 and there is video out there where a guy takes everything out the console

I think the biggest you could put in would be a 1.5Tb HDD just now... The cradle takes anything to 12.5mm, even though it says 9mm on the official stat. list. SSD would be cool but would cost a lot for even a relatively small drive?

Echoing the comments already made. You can't use an external drive with the PS3 but the HDD is replaceable. I'll be keeping an eye on how quickly it gets filled up but I'm more likely to just remove data, than opt for a larger harddrive

Please describe the nature of the abuse:
