I had 1.0 on a Samsung 830 SSD SATA III , 250GB drive I use for games. It loaded significantly faster than a standard drive, and I saw the largest difference with zone loading and cutscene loading. It helped out with character blinking during equip swaps as well to a lesser degree. It's a decent upgrade, but way more noticable in other games. Several games with normally long loading times have little tutorial tip messages during the loading screens that I can't even read now since the games load so much faster.
