Thanks to all the cleanup work you shouldn’t have to add any extra drives. For now I would say please don’t order new hard drives and only use what you already have connected and on standby. Next week all the data that was moved into the trash folder this week will be available for new uploads. I am trying to solve this question with math but there are to many variables. I guess we need to wait for the actual uploads to hit our nodes. At that point we should be able to calculate how big our nodes will grow. All we need for that is some data about the TTL distribution.
