The Blu-Ray Drive

The Blu-Ray drive that comes with Playstation 3 can read BD (Blu-Ray) discs at 2x (72 Mbps, i.e., 9 MB/s), DVDs at 8x (8.1 MB/s) and CDs at 24x (3,600 KB/s). As you can see this is a very simple unit (all Blu-Ray players have a minimum speed of 2x, so 2x here isn’t really an advantage).
