Former Dropbox employee, just correcting one assumption:
> Dropbox's peak traffic is 1,500 queries per second (QPS).
I can't speak to search QPS directly, but most individual serving hosts for file sync/retrieval were receiving tens of thousands of QPS. The overall edge QPS peaked at several hundreds of thousands QPS every day across all the hosts. So I'd guess that even just search is an order of magnitude higher than 1,500 :)
