The hardware you choose depends a bit on your workload - writes vs
reads, amount of cacheable data, latency requirements, etc..  What
sort of workload do you expect?

See for some general advice.

People typically have 8-24 GB RAM per node with 1-8 TB of storage, but
there are cases where bigger or smaller makes sense.  Don't overspec
your nodes - you'll be better off with more smaller nodes.

You can use SSDs if you need the random read rate, and SATA drives are fine too.
