Cubbit Review: Peer to Peer Cloud Storage and Zero Knowledge

Cloud storage has been around for a long time and yet for the most part it remains the same. But not long ago, an Italian company has unveiled a device that they promise will reinvent cloud storage as we know it. As I am somewhat suspicious, I decided not to fall for the trap and give it a try.

(R) evolving cloud storage?

Privacy. No monthly fees. Eco-sustainability. A ton of storage space, accessible anytime, anywhere, no matter what. These are the claims of Cubbit, claims that so far have helped them raise just over a million dollars on Kickstarter and Indiegogo and more than 10 million in total funding. Are these claims supported? Let's see.

First things first: Cubbit is not what you think. When I say cloud storage, what you are probably thinking of is some kind of service software like Dropbox or Google Drive. You get some GB for free and if you exceed the threshold-limit you have to pay. Not with Cubbit, at least until recently.

Cubbit is what is known as a peer to peer cloud storage service. Think BitTorrent. Like BitTorrent, Cubbit is based on a distributed infrastructure. To access the service, either you have a node or you use someone else's node. The same goes for Cubbit. To use Cubbit, either you have a Cubbit cell, in which case you only make a single payment, or you use the Cubbit software as a service application, in which case you pay monthly.

What is a Cubbit node? They are what they call the "Cubbit Cells." Basically, it's a hexagon-shaped storage unit that for just $ 419 gives you 1TB of cloud space, no monthly fees, with a 4-year warranty. But it's sure?

Super secure and super private cloud storage: zero knowledge

Cubbit may not be as fancy as Google Drive, but it is certainly safe. Unlike other services, they apply a "can't be bad" approach to your data. In short, they cannot see them, even if they wanted to voluntarily. And they do their best to make sure of it.

In the world it is known as zero knowledge cloud storage. It means that the service provider cannot snoop on your stuff, as your private information never reaches their servers. Normally, this means that it stays with the user, such as the home computer, which means that you cannot access it when you are away. But Cubbit has a solution.

Instead of storing your data on its own server, as Google does, Cubbit encrypts it and spreads it through a peer-to-peer network of Cubbit nodes - Cubbit Cells.

As a consequence, no one can access your files without your explicit permission. It also means that small pieces of your data are in other people's Cubbit Cells. Chilling, right? But if you think about it, it has always been that way. Your Dropbox files are not only stored on Dropbox's servers, but they are also accessible to Dropbox, the company, and all of its employees. This does not happen with Cubbit. Why?

Because whoever hosts your data in their Cubbit Cell only has a small part of your files. And this chunk is encrypted, and they don't have the encryption key. In fact, nobody but you has it, since the encryption key originates from the client

Sustainable cloud storage

La encryption "end to end" and "zero knowledge cloud storage" are not the only purpose of Cubbit. Respect for the environment is fundamental in his vision. Another thing Cubbit says about their service that caught my eye from the start is that Cubbit is green. How green? Isn't traditional cloud storage already green? Well no.

Today, cloud storage consumes about 250 terawatt hours each year.. And this excluding the effervescent market of cryptocurrencies. If you do the math, it is almost as much energy as Spain consumes annually. So no, traditional cloud storage isn't green, and it never has been. After all, it's a bunch of remote, always-on servers, why would it be green?

In fact, why should Cubbit be green? Is not the same? Cubbit's network also remains on to function. And then why is Cubbit greener? The big difference is that the network is peer to peer. Being distributed, Cubbit is more energy efficient.

When you save a file to Dropbox, it is stored on a Dropbox server. Where exactly? It's an unanswered question, as traditional cloud service providers don't say where their servers are located. But the point is, unless you live near a Dropbox storage facility, your data is most likely stored in some other country who knows where. This has strong implications considering that most of the energy consumption in data centers comes from the transfer of this data.

On the other hand, when you save a file in Cubbit, a good part of it is stored in the Cubbit Cells closest to you. Therefore, when you want to access your data, it will take a much shorter trip around the world. In short, Cubbit is a zero kilometer cloud.


Compared to most traditional cloud providers, Cubbit has three cool features that make it stand out from its competitors:

  • Private links: Like all other cloud providers, Cubbit allows you to share links to your Cubbit files. In Cubbit, they call them "public links." In addition, Cubbit also allows sharing private links. Let's say you want to send a link to some confidential file to Pablo. If you create a private link, Cubbit will return a link and, separately, your encryption key. To send the private link to Pablo, you will need to send him the encryption key as well. This makes file sharing more secure, as you can use two different channels to share the link, which means a gossip needs to hack you twice to access the file.
  • Selective synchronization: Selective syncing lets you decide which files are stored on both Cubbit and your different devices and which files are stored only on Cubbit. In this way, you can greatly expand the storage of your devices. If, for example, you save all your photos in Cubbit and activate Selective Synchronization, you can free up a lot of space on your mobile phone.
  • Catastrophe proof: What happens if there is a power outage or the device breaks and your Cubbit Cell goes offline? Do you lose access to your data and files? Not at all. Remember: your data is not inside your Cubbit Cell. They are distributed on the network. The incident that your Cubbit Cell goes offline has no impact on your ability to access your files.
  • Two-factor authentication: If you want to be super paranoid, Cubbit has you covered with two-factor authentication.

Should I get a Cubbit Cell?

If you are one of these people, you should get yourself a Cubbit Cell:

  • A privacy enthusiast: If you are very concerned about privacy, then Cubbit is for you.
  • A blockchain enthusiast: There are a ton of blockchain-based cloud services, but none of them work as intended or as claimed. Or, at least, they are not really usable to store your day-to-day files. Cubbit is the first distributed storage service that really works.
  • An aspiring NAS owner: if you already have a NAS, Cubbit may not be an option for you. However, if you've always wanted a NAS and never bought one, then you should seriously consider Cubbit. The Cubbit Cell is cheaper and much easier to use than a NAS.
  • A photographer / video maker: If you have a ton of photos and videos flying around, Cubbit is your holy grail. Most cloud providers don't give you as much cloud space as you need, and for all that space you would pay a fortune in monthly installments anyway.
  • A designer: If you are a designer, you already have little space in the cloud, unless you are a premium user, of course. If that is the case, Cubbit offers you all the space you want, privacy and all this for $ 0 a month, making a single payment.

After all, if you are a lover of technology and you believe that privacy is important, Cubbit is made for you. .

And if you haven't made up your mind yet, you can consider taking advantage of their 30-day warranty and money-back trial, not forgetting that right now you can try Cubbit with a 15% discount. As an icing on the cake, they also have free shipping, a 4-year warranty, and their customer service is very good.
