There are times when you need to think about the type of ps3 hard drive that you have to pick. Look up the Sata 2.5in hard drive since its PS3 uses a Seagate 2.5in Sata 5400RPM laptop hard drive. If you are choosing a new hard drive it doesn’t matter what brand you use either as long as its an 2.5in Sata hard drive. There is also a requirement for a 5200RPM although a 7200RPM will still work though some people have experienced overheating issues from the faster drive speed.
But then again when you wish to be on the safe side then you can pick out the 5200RPM ps3 hard drive. You will see that there is a good selection of compatible drives on the market with a 320GB being around the $100AUD mark and 500GB costing around $160AUD. When you are not in a certain hurry then you can try and look around for new technology advances with dropping prices.
