One option is a more DIY solution which will save you money.
You can buy a barebone Kimsufi box from OVH. I have had one for many years now, and here's what I did.
I bought a KS-5 in France (I am in US and did not have any issues paying with CC). You get to choose what OS to install - a Linux distribution is always a good option (I chose Ubuntu). So pretty much, you buy a dedicated host (that's 100 MBit up and down, unlimited bandwidth). The KS-5 server comes with 2 2TB disks in a RAID 1 configuration (Mirrored setup). However, during installation, you have an option to change the data volume to RAID 0 - which means you will get almost 4TB of storage. Of course, with RAID 0, there is no data redundancy. If any one of these 2 disks fail, the data will be lost (OVH support will replace the disk of course). To me though, that seems like an acceptable risk versus the benefit you get in getting a lot more space.
Since you get a blank system here, you would need to install rutorrent software yourself. There are however public projects out there on github that allow you to do that if you follow simple instructions. During all of this, it does help to know your way around Linux OS (commands etc).
What I described here would cost you $16.99 per month.
Again, this is not for everyone. Its a DIY, but for anyone who has technical knowledge and wants to do this themselves, this is a great option.
