All the research I did about 7200rpm HDs in a PS3 came back with the same answer, that you don't really see a difference in load, save, & install times. I would have to disagree with that. I just installed a Seagate Momentus 750GB 7200rpm HD in my PS3 & am definitely getting faster load, save, & install times. When I load a save file or create one the progress jumps right up to 100% & starts the game vs with my last drive (a WD 640GB 5400rpm drive) which would go to 50% hang there for a second then go to 100% and into the game. I downloaded Rainbow Moon tonight which is just shy of 2GB & it installed to my HD much faster than I've been used to with my old drive. Now granted you won't see as big as a difference between the 2 drive types on the PS3 as you would in a PC but there still is definitely a noticeable difference on the PS3. I will be installing my old WD 640GB 5400rpm drive in my friends PS3 soon. Once I do I will time some of the same processes from the same games & post back.
you do realize CACHE size also plays a factor in how a mechanical hdd operates right?
Your old HDD might have had a smaller 8MB cache size where as your new drive could have 16 or 32MB cache size.
Your research is quite, loose.
There is an OLD thread, where someone did actualy proper research with a 5400rpm drive and a 7200rpm drive using several games that had to install games to the hdd and even recorded their temperatures. They were also the same capacity and had the same cache size.
His end result is that the less than 10seconds of load time separate the two drives with small installed games, and barely a 20second difference with large installed games. The heat was the only significant constant as the 7200rpm drive was between 20-30*F HOTTER than the 5400rpm drive.
And the MAJOR difference between the two drives was the COST. the 7200rpm drive was $30 more than the 5400rpm drive.
The in grand scheme of things, loading a save file and creating a save file has little to do with a hard drive's speed
