I am leery of companies that offer you huge storage capacity costing you next to nothing. I used to have a tb cloud storage plan with SkyLab who shortly after went out of business. Then I bought storage from Zoolz who had a connection with SkyLab for a very small amount and just a little while ago got the message that Zoolz couldn’t maintain my storage at the price I paid for it and offered me the opportunity to maintain that storage but at a additional monthly charge.
pCloud on the other hand has been very good to me. I have 500 gb storage and had no problems for over 3 years.
Be wary of companies that offer you a tb or more of cloud storage for a small amount. They really can’t afford to make such offers and you will find yourself faced either with a company that goes out of business or one that will not honor the arrangement they made with you and offer to maintain your storage for an additional monthly amount. Both scenarios happened to me.
