unfortunately after doing research into all of those, their terms of service allows them to charge more or cancel your account after what they consider to be 'excessive' bandwidth usage, so i wouldnt consider them truly unlimited or unmetered. It doesnt seem virmach offers unmetered anymore, but I may reach out to them
I asked Hetzner specifically whether they'd have a problem if I saturated my dedicated Gb connection for a month, and they said no, it's mine to saturate.
I don't remember if this is on a dedicated box or a VPS, but IIRC it was dedicated and the VPS has a 3 TB/mo limit.
Hosts such as Leaseweb, nForce or Worldstream have 100TB+ plans you can purchase. If you're willing to spend quite a bit, they also offer truly unmetered plans. I've personally used all three of them, but never used more than 100TB a month.
