Herein, how big of a HDD can I put in a ps3?
You need to make sure it's a 2.5-inch serial ATA drive of 9.5mm height or less. In practical terms this means you can buy most 2.5-inch 500GB or 1TB slimline hard drives without any major issues.
One may also ask, can a ps4 use a 2tb hard drive? The PS4 has a 500GB 2.5-inch SATA HDD, the likes of which are usually found in a laptop. Your choice of replacement hard drive must be no thicker than 9.5mm, otherwise it won't fit in the hard drive enclosure within the PS4. That does limit your options somewhat, especially if you're looking for a 2TB hard drive.
Then, what kind of hard drive does a ps3 use?
SATA hard drives
