60 free Internet hard drives

Today, with the increasing development of the Internet, online network storage has become one of the most commonly used services, and some people even use them as network hard disks. I have introduced some before, but compared to this introduction or pale, this provides 60 types of online network hard disk memory, 40 of which I made a simple explanation, some of them provide unlimited storage space, some unlimited download, some single upload file up to 1.5GB, some support FTP client, the most regrettable is that they are foreign, You need some basic English. But upload and download you always know it, you use the online network hard drive is not the main use of these two functions?
