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.
One of them includes the old EE and GS chips, and the other contains the newer unified EE+GS chip, otherwise being identical.
The PlayStation 2 was such a hot item after its release that it was near impossible to find one on retailer shelves, leaving those wanting a PlayStation 2 to either wait or purchase the console online at sites such as eBay, where the console was being sold by many people for twice and sometimes five times as much as the manufacturers listed price.
There are also some disputes on the numbering for this PS2 version, since there are actually two sub-versions of the SCPH-70000.
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.
In some markets it also integrates a modem.
The PlayStation 2 holds the record of fastest selling video game console ever, 100 million PlayStation 2 units were shipped in only five years and nine months, shattering the previous record of nine years and six months by the PlayStation.

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).
Only a few million users had obtained consoles by the end of 2000 due to manufacturing delays.
Since the V12 version had already been established for this model, there were some disputes regarding these sub-versions.
The PlayStation 2 had a difficult start.
V3 has a substantially different internal structure from the subsequent revisions, featuring several interconnected printed circuit boards.
