I'm not such a big fan of SQL.
However I am beginning to be a big fan of RRDtool. It's designed
explicitly for the purpose of storing relatively(*) large amounts of
SNMP data in ways that make it both quick to store and easy to retrieve
(it of course stores in the the "smart" way):
(*) One person reports updating a database with ~17,000 new values every
minute, though I don't think the number of rows kept was reported.
