Great point. The 10s of GB was anecdotal data from a CarrierIQ recruiter.

If we go by the official letter you've posted and assume conservatively CarrierIQ has only 1 Petabyte of data, and that they've been collecting since 2006 (when they received their Series A), they've been collecting 456 GBs of data per day. Its probably more than that today since the data collection rate has surely accelerated over time.

That's an order of magnitude beyond 10s of GB per day.

Well realistically they would not have been collecting 456GB per day from day 1. They would have grown from almost nothing, which means that today they're probably collecting around a terabyte per day. That's two orders of magnitude, 7KB per user per day - and could definitely include all keystrokes of all users.
