More Hard Drives or BIGGER Hard Drives

I’m upgrading my home server to a 24-bay 4U case and have some extra drives sitting unused. I’m thinking of utilizing them to make a small amount of money. I can either use 3 × 4 TB drives or 2 × 6 TB drives . Which setup would you recommend, and how should I configure them? From what I understand, 3 separate nodes may be better than 2, but I’m not sure why. How does this affect Storj payouts?…
