Sony's Jack Tretton was recently asked to justify the price of the PS3 hard drive when a stand alone drive can be found for much cheaper elsewhere. Tretton responded by saying that it is within the context of games consoles and the 20GB Hard Drive for Xbox 360 is infact $100.

1UP: With the new 80GB SKU, $59.99 comes from MotorStorm, the remaining to make up the $599 is only 20GB. How do you justify $40 for a 20GB hard drive when you can buy a 20GB hard drive for $10 on Newegg.com?

Tretton: I guess we have to talk about gaming consoles. Unless I am incorrect, I believe the 20GB add-on for the Xbox 360 is $100. I guess you have to look at in relative terms to gaming SKUs and we think $100 is a pretty good value with MotorStorm and the 20GB packed in, but they have a choice and if that isn't a good value for them and they prefer to buy the 60GB at $499, that certainly gives them that option.
