For what it's worth, I've used MapD to query ~100gb of GPS data. I was running queries where I was looking for ever point within a given distance of a source point (queries often had 10s to a hundred-something source point s), within a given time period. MapD would scream through the hose queries ludicrously fast, I don't think I ever had a query run for longer than half a second, 0.7 seconds tops. While I wasn't running the most complex queries, I also didn't have to do any complex setup (I literally just loaded the data in via command line, single table, nothing special), it was awesome.
