First off, it's been documented already that install times get cut by as much as half on a PS3 with an SSD as opposed to a PS3 with a standard, mechanical hard disk. And that's because - at least from the breakdown - GT5 likes to install the game, and have separate install sessions for different cars and tracks. Honestly, with how they broke it down, it sounded a lot worse than how MGS4 requires a separate installation for every different act that you decide to play. It pretty much makes those one-time, super-large installs that some games make sound like we're getting off easy by comparison.
And Gran Turismo 5 is a large game. Not quite as physically large as God of War 3 (which measured at 40GB's
on this database vs. GT5's 19GB of data ), but you'd think the guys at Polyphony would have figured out a more elegant way of handling it, like so many of Sony's third-party devs have been able to do. My
ideal would be no required installs whatsoever, but given that Sony did rather shoehorn the slowest possible BD drive in a PS3 just to validate that part of the company's reason to exist, I'm still surprised that
every game doesn't just have mandatory installs.
And as far as my sig? Please... I've been a long time Playstation user, and as such, I have just as much right to complain when they screw things up as much as you have to praise when they do things right.
If you don't believe me about the heinous way in which Gran Turismo 5 handles its load times on an HDD vs. an SSD,
here is the first google search result, with plenty of pictures to demonstrate.
