There's no reason to use md5 if you don't care about security and only want speed. Non-cryptographic hashes are incredibly fast to calculate and there are far faster hashing algorithms if you want to go that route. Using md5 is a "I don't want to think hard" answer, and if you don't want to think hard, then you might as well be secure in your default answer.
