Here is sign up link and you get 30GB free storage on Hubic. More than Dropbox, Google Drive, SugarSync, Cubby or Box but combines features of each while keeping it simple. Use this link and you get 30GB assigned (that is 25 + 5 GB)..... https://hubic.com/en/offers?referral=ERDMMU
Just so that you know.. why they are... Hubic is provided by 3rd largest hosting company in the world, with 150,000 servers, so they are not going to go anywhere.
(If anyone signs up using my referral link, you can change the language of Hubic to English or other language in the right upper corner of the website.)
SugarSync offers up to 80 GB for free if you choose to offer a bit of your space to host others' files. And... do I feel a bit of spam in your post?? Yeah, definitely.
Here is a referral - https://hubic.com/nl/offers?referral=CYHNPO ..... Sign up with this link and you get 30GB signup space instead of the regular 25GB at Hubic. So that's 30GB space with signup and additional 25GB for a total of 55Gb with additional 5 referrals. Good luck! https://hubic.com/nl/offers?referral=CYHNPO
