The Nintendo Nsider Forums are lighting up with glee (and spilling onto Digg) at how horribly terrific it would be if Ridge Racer 7 required a 5 GB install on PlayStation 3's hard disk drive. Some generous (in favor of Sony) math calculates that the install would take 9 minutes and 46 seconds. The assumption is most PS3 games will require HDD dumps, forcing users to constantly install, erase, and reinstall -- these data chunks would fill up the drives fast; certainly the 20 GB model.
Here's what we know: Ridge Racer 7 will have an optional 5 GB HDD installation feature that's in place to speed up load times. Currently, Ridge Racer 7 and Genji (4 GB install) are the only games known to include this option. While this will almost certainly change, there's little reason to believe that HDD dumps will become a PS3 standard (unless you buy Sony's "it's not a console, it's a computer" mumbo jumbo).
Anyways, waiting 9 minutes and 46 seconds for data to install isn't as agonizing as we'd sometimes like to believe; especially if it's a one-time (or once in a while) procedure. On that note, let's wait this conundrum out for a while longer, watch how it develops.
