How to configure my servers

Which way can have better reword?

Configuration 1:
One server has 4 SSD disks, 1 TB for each disk, 4TB of space in total.
This server is configured to do multiple disk farming.

Configuration 2:
Four servers in total, each server has 1 TB SSD disk respectively.
And the four servers are configured to do single disk farming for each server.

Which configuration is better to win the subspace reward?

Either should work, but I would put the 4 drives in the server with the best cpu personally.
