Unlimited hosting is not unlimited.

Web hosting providers with “unlimited” disk space and “unlimited” bandwidth are not being upfront with you. In fact, they are lying to you. First, there’s no such thing as unlimited disk space. All storage has limits – whether your host uses local storage or SAN storage. 

Check the Terms of Service and Acceptable Use Policy. This is where you’ll find the true limits of “unlimited” plans. You may find that there is a restriction on the type of files you can have in your account and how they must be used. More often than not, you’ll find that while your disk space is unlimited, you will actually have an inode limit.

1 inode = 1 file or directory. That means if you have a 250,000 inode limit, your account can only contain a maximum of 250,000 files and directories! Web hosting accounts have many more files than you might think – it’s not just your website. Log files, databases, emails, cache files, and more will all count towards your inode limit. That doesn’t sound very unlimited, does it?
