My project is to build a AI(Artificial Intelligence) system in which i am planning to have a raspberry pi or Intel i3/i5 processor.

Raspberry pi is small and efficient but i don't know whether it can support 2 TB or more external hard disk.

Where as in Intel i can have internal hard disk and at the same time external also and will be more faster with 2gb or 4gb RAM.

Which is better Raspberry pi or Intel,is it possible to stimulate my ubuntu in Intel processor.

the main reason using processor it to give the system decision making capability ,understanding and analyzing capabilities using different algorithm's .my processor should analyze the condition take proper steps in running the appropriate application
