It means that is the max storage you can get for these hosters, however for some hoster this is also the max size for a single file which you want to upload. But you can create a second account or (if avbl.) buy pro to get more storage.
My question was just to point you to declare such limits properly! File size and Storage max, are just 2 different 'worlds'!!
I heard some pretty great things about Pomf.cat No file expiration, 75MB limit, direct file download, and no account needed.
