title_body: Relay Node & Block-Producing Node, which one requires more Hard Disk capacity? As a follow-up to this questions
  Say, I have a SSD of 2TB, which of the two nodes do I have to connect it to? BP or Relay Node?
upvoted_answer: Both nodes need to download the Cardano blockchain and therefore both nodes need some disk space. Currently the space needed is ~25GB.
