Too bad the next generation of consoles are still going to use HDD instead of SSD for storage.
I think (aside from the cost of SSD still) they go with HDD because of the longevity. SSD isn't yet optimised for gaming. Super fast as it may be, the disk degrades very quickly with gaming.
Maybe not all game types, but any game that relies heavily on the disk it's installed on is killing.
I've stepped away from SSD for games when the one game I had installed on it caused it fry within 2 years and the manufacturer stating it exceeded the benchmark usage by a factor of 4 based on a 4 year life cycle.
