It even claims that you can use generic hard drives, though it does say "Proper operation is not guaranteed for all models."


It's a 2.5 inch SATA drive, and yes it is user replaceable and upgradable. If you add a new one, the system firmware allows you to format it properly for PS3 use, or split PS3 and Linux use. If you do upgrade it, everything functions the same, and you aren't banned from the online network, like you are if you replace your 360 hard drive with a larger one.
