For reasons of completeness, I cite a recommendation from another thread:
Mega.co.nz (50 GB free)
PS: I found out mega.co.nz was founded by a fat, childish, german guy, who is a criminal, Kim Schmitz (alias Kim Dotcom). He went into prison and when he came out, he claimed he had hacked NASA and pentagon systems. He then got jobs form security enterprises. Later it turned out, that he doesn't know a lot of coding and has his people doing it. He is also famous for hosting several illegal file sharing platforms for movies (not that I judge this) that got shut down one after another, some still exist. He always keeps on saying how great he is and still in fact he has smart people under him that code for him. (He lives on the knowledge of those people - It is a difference when people like Steve Jobs become Gods, because they have their people vs. being a swindler and a fat laughing child). Sorry, for being overly moral.
German Wikipedia also notes that this site claims to be 100% private, in fact your personal data can be sold to companies who trade with it. Also there seem to have been some easily doable Java-exploits.
Bottom line get your information about mega.co.nz and decide yourself.
