If I just want to download the complete FF tables, how much drive space do I need?
1,25TB for compressed files then other 1,25TB for the actual files
I did it a bit differently. I extracted the links from the source page and downloaded them in stages, i.e., individual archives. I then unpacked them to the target drive, and then deleted them from the source drive. In this case, even 150-200GB on the source drive and just that 1.25GB on the target drive would be enough.
