can't imagine it's that big. srtm data for US is in 30m resolution is ~ 15G in compressed form. maybe the full USGS dataset is in multiple formats or in an uncompressed format.
For some regions they have higher accuracy available but that should still be in the 100G range

no experience with it but sounds like an interesting option
