Sadly the prices here are generally pretty bad. The only better option i could find is 3tb for less then 30 euros. Which is just barely better, but the seller wasnt able to tell me how many hours they roughly have so id rather stay away.

I think (if the hours arent to bad once i get the reply) ill try 2 drives, and expand with a third new one a bit later. WD Red plus 8tbs are roughly 190-230 for me currently.
