PS3's Genji uses HDD to quarter load times

Before jumping into Genji to deal some massive damage to historically accurate giant crabs (nyuk nyuk) during Sony's Gamer's Day event on Thursday, MTV News' Stephen Totilo noticed a curious menu option:

INSTALL

What's this all about? Totilo writes, "Also unexpected was a feature in Genji to install the game, committing 4GB of data from the game's Blu-ray disc to the PS3's hard drive -- a three-minute one-time-only procedure available from the game's start menu that a Sony rep said cuts down in-game load times from about 15 seconds to four seconds."

So, regardless of the debate about the relative read speeds of 2x Blu-ray drives and 12x DVD drives, we can all recognize the obvious benefits of having a hard drive included by default. Why Genji appears to be the only title sporting this option is another question. Did excessive load times in the PS3's first finished title necessitate extraordinary measures, or will most games offer this time-saving option, Ã* la PC games.
