At this point in time (2022) I consider everything below say 40TB not big (textual) data at all. It can be compressed 40TB -> 10TB (or less) and that fits fine on a single 16T drive.
For many questions, you won't need all the raw data, so you end up with some form of projection of the data that is maybe 1/10 in size, so 10TB -> 1TB. Heck, if you tune GNU sort a bit, it will blast through that TB quite quickly.
