Sony have really pissed me off recently. They used to be so respectable and reliable.
My little brother got a PS3 for christmas (the 12GB version because we're not well-off).
Turns out you're forced to install every game you play nowadays, so after playing 4-5 games, the hard drive is full, meaning he can't play any more games until he buys another 2.5" drive to put in there.
After dropping £40 on a 500GB WD Blue 5400rpm 2.5" drive, we realise you need to buy the "OFFICIAL SONY DRIVE CADDY" or some ****. £20 to get one in Britain.
Ended up bodging the hard drive into the bay using a variety of spares/scrap computer parts from my PC building days.
Even Microsoft are more honest than Sony are nowadays.
I don't know about the new models, but the first PS3 (the fat one) allowed you to simply install "any" 2.5" drive that fits... The physical size and storage size may be limited like with some old computers... Max storage size depends on the sata controller or the "bios"...
You do know it's possible to simply uninstall the games? Then install them when needed... The reason for installing is many thing... Loading time is one... Loading from disk, even blu-ray is not as fast as from a hard-disk... Deleting games should not delete saved games!
And FWY, Microsoft will in no way, ever be more honest than Sony... You can see the space required on the back of each game...
Consoles used to be the only way to play second-hand games, no keys, no registrations... It was easy as hell to lend games to friends and family. And when you got bored, you simply sold it...
Used games stores has become a big deal. Some stores even ask for used versions of new games, so if you buy a singleplayer game on it's release date, complete it within a week or so, go down to your local game store, trade it in for a gift card, you can almost get the same amount back as you paid for it.
The store now has an almost new game they can sell quite close to the retail price... One thing to remember, you got a gift card that you have to spend in this store!
Every time they earn money on a used game or you sell a used game privately, the company behind it doesn't get a single penny!
Why do you think the retail prices are so high for console games and not for PC games? PC games are usually lock to an account! Console games are not!
If this changes... And second-hand games no longer works... You would see some form for drop in price, simply because the sales total would go down... (I know second-hand games aren't counted as sold copies, but knowing you have to by new expensive games would keep certain people from buying the console and thereby games)
