Hi, Generally speaking, 48/64GB RAM with 20TB storage is enough strong for typical usage of Riak CS, like yours. I would like to mention that too large disk size per node with narrow bandwidth may lead to less availability - time to recover degraded replicas in case of node/disk failure may take longer (because larger disk means longer time to recover). That should not be longer than MTBF. To ensure the availability, please make sure you have 5 nodes or more.
