Say, I have a SSD of 2TB, which of the two nodes do I have to connect it to? BP or Relay Node?

Both nodes need to download the Cardano blockchain and therefore both nodes need some disk space. Currently the space needed is ~25GB.

It grew from 7 to 10.5 GB In addition it depends on your logging settings and retention policy how much additional space is needed.
