A:AnswerThe PS3 and ps4 can't fit a desktop hard drive but if you get a laptop drive or a solid state, both of those can be formatted and fit into the consoles. Due note as far as rpm speeds, heat is always a factor as the drives get faster. It is okay to have a 7200 rpm drive in a console, it'll run a little bit warmer than the 5400 rpm stock drives the Playstations include but it's safe and the speed difference will be worth it. If you can though invest in a good size solid state drive for the ps4. Highly recommend it! Have fun and game on.
A:AnswerI did some comparisons between the drives, and it would appear from WD's website, Mainstream HDD's sometimes come with a variable speed rating to compensate for power usage and heat. In laymen's terms, the drive is capable of 7200 rpm, and will use it when it has to, otherwise it will spin down to a lower rate when idle. It also improves on the life span of the drive. There is also sometimes a difference in warranty, but with these two drives, they are the same. 2 yrs on parts (limited) and labor.
