The PS3, aside from being a game console, is also a pretty powerful media center. Its worth noting, all that you need is a drive capable of 5400rpm and 1.5gb/s. All of the PS3's system data is stored away safe and sound, far away from your shaky, nervous hands. If you use the correct tools, take your time, and follow directions, it'll be fine.
But a media center with limited memory would be pretty pointless, so I yanked that tawdry little 80gb drive and replaced it with a hulking 250gb drive. You could spend more money on a drive that's capable of 7200rpm and 3.0gb/s, but the PS3 will only utilize it at the aforementioned speeds, so its pretty useless. If you use a butter knife for a screwdriver and rush through it....yeah, you'll probably screw something up. Precision Screwdriver Set - Really, don't try to use that big screwdriver in the junk drawer.
In practical terms this means you can buy most 2.5-inch 500GB or 1TB slimline hard drives without any major issues.
2TB hard drives are often a little too tall, but then that capacity is arguably overkill for the aged PS3, especially as the drive will usually cost you at least £85 (US$115, about AU$167).
If you opt for a 5400rpm drive, another spec you should see listed alongside capacity, you'll get similar performance to the standard PS3 HDD.
