IMHO the size of the DB is less relevant than the query workload. For
example, if you're storying 100GB of data but only doing a single
index scan on it every 10 seconds, any modern machine with enough HD
space should be fine.

If you give us an idea of the # of queries you expect per second, the
approximate mix of reads and writes, and some idea of how complex the
queries are, we might be able to give you some better advice.
