how do i know what gb my playstation 3 is
PlayStation 3 models There are several original PlayStation 3 hardware models, which are commonly referred to by the size of their included hard disk drive: 20, 40, 60, 80, or 160 GB.[3][4] Although referred to by their HDD size, the capabilities of the consoles vary by region and release date. The only difference in the appearance of the first five models was the color of the trim, number of USB ports, the presence or absence of a door (which covers the flash card readers on equipped models) and some minor changes to the air vents. All retail packages include one or two Sixaxis controllers or a DualShock 3 controller (beginning June 12, 2008[5][6]), one Type-A to Mini-B USB cable (for connecting the controller and PlayStation Portable to the system), one composite video/stereo audio output cable, one Ethernet cable (20, 60 and CECHExx 80 GB only) and one power cable.[4][7][8] All models support software emulation of the original PlayStation,[9][10] but support for PlayStation 2 backward compatibility diminished with later compatible models and the last model to have integrated backward compatibility was the NTSC 80 GB (CECHE) Metal Gear Solid 4 Bundle.[11] Compatibility issues with games for both systems are detailed in a public database hosted by the manufacturer.[12] All models, excluding the 20 GB model, include 802.11 b/g Wi-Fi.
