Storage Capacity
Sony produced the Fat PlayStation 3 with five data storage capability choices during its production run: 20GB, 40GB, 60GB, 80GB and 160GB. The Slim PS3, at the time of publication, has four: 120GB, 160GB, 250GB and 320GB. Only the 160GB and 320GB are in production at the time of publication, with manufacturer's suggested retail prices of $300 and $350, respectively.
USB Ports
The 20GB, 60GB and 80GB versions of the Fat PlayStation 3 -- released on November 2006, March 2007 and August 2007, respectively -- were designed with four USB 2.0 ports to connect up to four vibration-feedback game pads that Sony designed for the PlayStation series of game consoles called Sixaxis and DualShock. Other PlayStation 3 models have two USB 2.0 ports instead.
Backwards Compatibility
The 20GB, 60GB and 80GB models of the Fat PS3 possess the ability to play PS1 and some PS2 games. With the arrival of the Fat PS3's 40GB model on October 2007, however, PS2 compatibility was removed. The feature was also missing on the newer 80GB model, which debuted on August 2008, as well as later Fat PS3 models and the PS3 Slim.
