We easily support 10s of millions of writes and reads against Mongo per hour on a very small (single digit) number of shards in the cloud (i.e. crappy disk I/O). While that is around an order of magnitude less than 30k a second I would be surprised if we couldn't scale mostly linearly by adding shards.P.S. If your stack is KV then you should use a KV store.

MongoDB aside, why should you assume? You should test the heck out of any DB solution before using it to base your product on.
