Due to its thinner profile, it does not contain the 3.5" expansion bay, and therefore does not support the internal hard disk drive but due to the presence of USB 2.0 ports an external USB Hard disk can still be used, and now uses an external power supply, like the Gamecube.
When the PlayStation 2 launched in Japan in March 2000, Sony sold 980,000 units over the opening weekend.

There is also now a V14 model (SCPH-75001) which contains an integrated EE and GS (disputed - see talk page) , and different ASICs compared to previous revisions, some chips having a copyright date of 2005 compared to 2000,2001 for earlier models.

V7 and V8 are also similar, and V9 (model number SCPH-50000/SCPH-50001) added the Infrared port for the optional DVD Remote Control, removed the widely unused FireWire port, added the capability to read DVD-RW discs, and a quieter fan.
Available in November 2004, it is smaller and thinner than the old version and includes a built-in Ethernet port.
Many analysts predicted a close 3-way matchup between the PS2 and its soon-to-be-released competitors Microsoft Xbox and Nintendo GameCube, noting that the PS2's graphics were inferior but that it had the advantage of a head start, and had a wide assortment of games of every genre (Xbox's strength was in its hardware; GameCube was the cheapest of the 3 consoles).
One of them includes the old EE and GS chips, and the other contains the newer unified EE+GS chip, otherwise being identical.
The PS2 launch seemed unimpressive and gaffe-prone, compared to the well-planned launch of the Sega Dreamcast, which was making a genuine attempt to woo developers and which had better launch titles.
These included a PCMCIA slot instead of the Expansion Bay (DEV9) port of newer models.
V3 has a substantially different internal structure from the subsequent revisions, featuring several interconnected printed circuit boards.
