Double digits PB/d is way more than 10Gb/s. 10Gb/s is about 100TB/d, so off by two or so orders of magnitude. So, OK you say, let's bond 100Gb/s links or some

Double digits PB/d is way more than 10Gb/s. 10Gb/s is about 100TB/d, so off by two or so orders of magnitude. So, OK you say, let's bond 100Gb/s links or something, but you need machines that can do that, too, and now you can download one copy of one day, per day, of data -- maybe, plus you need all that storage for that one very very vulnerable copy. Can't be done. Big data is hard to deal with. You can't just download the stuff.
