That makes sense. Ive got 25Mbps up and an array of 8 drives so i dont ever get anywhere close to being limited by the drive speed when seeding, ive got to set the upload limit well under what a single 7200rpm drive can saturate. I manage to get lots of torrents up to a pretty high ratio and keep a good ratio on all my private trackers with a 1.5 MB/s upload limiter though, so maybe you could just turn your limiter to... lets call it 20MB/s? A 7200 rpm drive should be able to do atleast 80MB/s, so if you just set a reasonable limit you will still be able to seed out more than your fair share of data without messing up your viewing experience. Then you can put all your drives in one pool in the storage server and de-duplicate everything.
Unless you are just REALLY into having the high score on seeding ratio, i am not sure allowing qbittorrent to saturate your hard drive bandwidth is necessary, although as a member of the community i greatly appreciate your efforts to seed so much data!
I moved to air vpn when mullvad disallowed port forwarding over the vpn and I have been pretty happy. When i looked into security audits it seemed to be the closest to mullvad in quality, while still letting be get a port though the VPN. I did not look into their founders politics. Until reading this today i had still been reccomending mullvad to all my friends that were not hosting stuff and im pretty pissed that i had been doing that now.
