Has anyone here heard of some of the new(ish) decentralized/distributed cloud storage services, such as Storj
They're cheaper than, e.g., Amazon S3, Google Cloud, Microsoft Azure, etc., and have additional features such as privacy, since your data is broken up into little chunks, encrypted, and distributed across the drives of many different "storage farmers" who rent out their disk space.
Sia seems to be a lot cheaper, but also seems a bit more convoluted to set up. Storj is more expensive (than Sia, but still cheaper than Amazon S3, etc.) but appears to be fairly simple to set up. They've even partnered with FileZilla so now Storj services are built in to the latest version of FileZilla. Storj also offers 25GB free for 12 months. They might be worth looking into if you need cheap cloud storage.
Full disclosure: I recently learned about these services and decided to allocate some of my HDD space for a Storj farm to get an idea of how it works. So I get paid a few dollars worth of the Storj cryptocurrency each month for renting out some space on my HDD. As far as I know, there's no way to choose which farmer your data gets sent to, so there's no way for me to directly benefit from referring anyone. That said, there's a chance that if you do use Storj, some of your data could end up on my HDD and I will be compensated for renting out my space to you.
I also tried to rent out some space using Sia, but as I said, it is more convoluted. It requires you (as a "farmer") to put up some collateral and I wasn't sure enough that I had things configured correctly to want to risk losing my collateral.
