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....

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:
