Too high. See http://news.appbase.io/scaling-elasticsearch-writes/ for example:

> In doing these tests, we indexed over 1 billion documents under just two hours. The peak merge rate we saw was 129 MB/s, yes our ElasticSearch cluster on a 24 node setup is gobbling data at this speed.

> Most mind boggling of all: At our peak sustained ingestion rate, we would have added over 13 billion documents in a single day and this would have cost us a mere USD 244.

Their test documents are much smaller (100 bytes) than a typical web page but if you multiply that figure by 50 to get to 5kb documents (probably a realistic average web page size minus all markup and assets), you get 12200$ for 13 billion documents or 1220$ for 1.3 billion documents (assuming that scales linearly). I'm probably way off in my estimate myself but I'm convinced that a few thousand dollars is much closer than the proposed 12M$.
