PlayStation 3

The PlayStation 3 is the third home video game console produced by Sony Computer Entertainment and the successor to the PlayStation 2 as part of the PlayStation series. The PlayStation 3 competes with Microsoft's Xbox 360 and Nintendo's Wii as part of the seventh generation of video game consoles. It was first released on November 11, 2006, in Japan with international markets following shortly thereafter

Major features of the console include its unified online gaming service, the PlayStation Network, its multimedia capabilities, connectivity with the PlayStation Portable, and its use of the Blu-ray Disc.

The PlayStation 3 features a slot-loading 2x speed Blu-ray Disc drive for games, Blu-ray movies, DVDs, CDs and other optical media.It was originally available with hard drives of 20 and 60 GB (20 GB model was not available in PAL regions) but various sizes up to 320 GB have been made available since then (see: model comparison). All PS3 models have user-upgradeable 2.5" SATA hard drives.

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. 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 and/or a DualShock 3 controller (beginning June 12, 2008), one miniUSB to 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. All models support software emulation of the original PlayStation, but support for PlayStation 2 backward compatibility has continually diminished with later models and the last model to advertise integrated backward compatibility was the 80GB Metal Gear Solid 4 Bundle. Compatibility issues with games for both systems are detailed in a public database hosted by the manufacturer. All models, excluding the 20 GB model, include 802.11 b/g Wi-Fi. In addition to all of the features of the 20 GB model, the 60 GB model has internal IEEE 802.11 b/g Wi-Fi, multiple flash card readers (SD/MultiMedia Card, CompactFlash Type I/Type II, Microdrive, Memory Stick/PRO/Duo) and a chrome colored trim. In terms of hardware, the 80 GB model released in South Korea is identical to the 60 GB model released in the PAL regions, except for the difference in hard drive size

Numerous accessories for the console have been developed. These accessories include the wireless Sixaxis and DualShock 3 controllers, the Logitech Driving Force GT, the Logitech Cordless Precision Controller, the BD Remote, the PlayStation Eye camera, and the PlayTV DVB-T tuner/digital video recorder accessory.
