The standard HDD that comes with your PS3 is 5400 rpm -- not bad, but not the best on the market. Ps3Fanboy has stumbled across a write-up detailing the addition of a different hard drive, running at 7200 rpm, and its effect on a various array of games and other such things. While they wouldn't recommend you all rush out and do this, as long-term effects can't possibly be gauged just yet, it's still interesting to consider the ways Sony fans can customize their console to be unique. Here is an outline of the results:
* Temperature testing against the two hard drives yielded a minimal difference; no overheating will occur with a 7200 rpm drive, ostensibly.
* Installing demos after downloading off the PSN had an average of ten seconds shaved off due to the higher rpm drive, except that Tony Hawk demo, with destroyed over forty seconds of install time. Impressive.
* Loading games generally yielded minimal results, unless you consider 2 seconds of load time a big deal.
In conclusion, yes, a 7200 rpm drive does increase your PS3's performance.
