Shopping for a new PlayStation 3 can be difficult because of the various models available. This guide looks at the differences in the models currently available. At present, there are 40GB (model CECHHO3), 60GB (model CECHC03), 80GB and 160GB (CECHP01) models available in the UK. Let's look at the differences:
60GB model has backward compatibility. You may play most of the PS1 and PS2 games. Most of the PS2 games are supported by the 60GB PS3, and the majority of PS1 games can also be played, though this cannot be guaranteed.
40GB, 80GB and 160GB PS3 do not have backward compatibility because Sony did not put the PS2 Emotion Engine into the PS3.
There have been reports that Sony will make the PS3 backward compatible through 100% software emulation. Details have yet to be confirmed. When it becomes available, this will be achieved via firmware update through the PlayStation Network.
USB Ports Availability
40GB PS3: 2 USB ports
60GB PS3: 4 USB ports
80GB PS3: 2 USB ports
160GB PS3: 2 USB ports
Memory card slots
Only the 60GB PS3 has memory card slots (Compact Card, SD/mini SD Card and Sony's MemoryPro).
For 40GB, 80GB and 160GB models, you may use a card reader to plug into a USB slot to read memory cards.
SACD Support (Super Audio CD Support)
Only the 60GB PS3 has SACD support. This is because the 60GB model contains Graphics Synthesiser GPU.
Wired and Wireless Networking
All models feature Gigabit Ethernet, 802.11b and 802.11g wireless networking. Wireless networking support WEP, WPA and WPA2 encryption technologies.
To improve your internet connection feeding into the PS3, you may wish to use CAT6 instead of CAT5 ethernet cable and Gigabit router or wireless router.
