I have tried almost every cloud storage available but eveyone of them has some issues like less space, ads, speed, account termination etc but then I found DROPBOX and now I am using Dropbox from a while and I have not faced any kind of issues yet. It is fast, provides 1 tb of space and its absolutely free. I liked it so much that I upgraded it at very low cost and it I have handful of features more like direct file links. Now I can even store my files in here and link them to my website directly. Dropbox made storing, linking and sharing thousands of files so easy. I love using it.
