How much data do you download per month?

Nowdays 50-100GB (closer to 100, but depends of the content, free time etc.), earlier a lot more.

between 3-6 tb.

between 1-10tb

Probably only 20-30gb. Sometimes I just grab a heap of stuff to make sure I have some up to date libraries and then sit on it for a good while.

Depends on the month. Usually it's a game, so around 50-60GB a month or so.

A bit over 2TB every month, counting both download and upload.

Usually around 1.5TB (Upload and download)
But sometimes it crosses 3/4TB too

Those are rookie numbers ahah

I don't measure it, but this month it's probably in the 200-400GB range so far.

700GB+ - mostly movies
