HDD Replacement Test
One of the great things about the PS3 is that it uses a SATA hard drive that you can replace yourself. So whether you bought the 20GB PS3 or the 60GB version, you can update it to any 2.5″ SATA hard drive you feel the urge to buy. And that’s exactly what the folks at Japan’s Impress Watch did, and IGN gave us some coverage.
First off, according to Impress, the 20 Gig PS3 includes a Seagate LD25.1 hard disk running at 5,400rpm and with a cache of 2MB. The 60GB PS3 has a Seagate Momentus 5400.2 HDD at 5,400 RPM with a cache of 8MB.
Impress Watch replaced their PS3’s HDD with a Seagate 7200.1 series 100GB hard disk running at 7,200rpm and with 8MB cache. It seemed to work flawlessly. They didn’t notice any speed increases when installing something from BD disc to HDD. Duh! That’s why the HDD is used as a cache. The real question is, once something is on the HDD, is it any faster? The answer is that yes, it is faster, but only a tiny little bit, and only over the 20GB version. But maybe some other HDD’s will give different results.
