Rainbow tables store all the predetermined hashed along with the corresponding text.....They signify the trade-off between memory and performance.....
Rainbow tables are of 50-100 GiB (Depending on the amount of information it stores) and can help you find the plaintext of the hash within seconds....

I knew that method, but I didn't know its name was "rainbow attack".
You say 50-100 GB but I heard that the tables had sizes which are in units of TB, and only a few supercomputers in the world have it.

No, servers these days support TB of storage. All major RDBMS's support data files in TB!

A lot of people use PHP for md5(), and when they use a C++ implementation it doesn't always return the same hash.

This implementation's hashes match that of php:
