Would an upgrade to a faster upload speed mean a migration of your box if is has already been moved to the new data centre? or is it a simple case of adjusting the resources associated with it?

I am guessing when you say NVME buffered storage i am guessing you mean you are using caching  drives?

The plan I am really hoping you introduce  would look similar to  the following 

5 gig DL  / unmetered up
5TB  storage 
Media 4K  (not capped similar to the avenger)
6 gig ram

25 TB upload/month

That has got to be worth around    €44.99   month, certainly no more than that IMO

Going from the Avenger to the avenger pro i would consider it almost a downgrade to 1080p,  the super villain is less storage but faster, the ace is out of the question as the cost is almost double :(
