An operating system's primary goal is to provide an abstraction for applications to interact with users (get user input), and interact with hardware devices (provide output for users). At the most basic level, all operating systems provide these two types of services. Additional services, such as security, are a feature only on certain operating systems. Generally speaking, operating systems provide access to permanent storage systems, such as disks, printers, and keyboards.

Backwards compatibility and able to support upto a terabyte
Yes, an early PS3 model of the 80GB with 4 USB ports could play some PS2 game titles. The 2 USB port PS3 80 GB models do not play PS2 games and software or hardware changes can not provide backward compatibility to them according to Sony
Using a Kingston card reader for Kingston cards is most likely to provide compatibility, but using another brand shouldn't preclude the viability of compatibility.
