We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time (tm) ). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.

What isn't shown in the chart is the price for larger drives. We've had prices in the thousands (discussing dollars), then in the hundreds, then the HUGE difference was made from the crisis started at the end of 2011, when we started with 2TBs going towards 25/TB (ok, usually 30+ but in any case way under 100 for a 2TB drive). The prices went up and then barely recovered. Not only the maximum capacity didn't increase too fast but also the price per TB didn't decrease much. We aren't nitpicking here that it's between 25/TB and 15/TB or 35 and 12.5, we're talking orders of magnitude like it was the case for these intervals before. There isn't anything worth mentioning into double digits anymore (spinning drives under $100). And it isn't that there wasn't inflation in the 80s, 90s and 2000s, this thing with nearly zero inflation was just some part of 2010s.
There are people even now (well, as of yesterday) in this sub that would recommend 4TB spinning drives for 135 Euros. That is when you can have SSDs at around 150 with the right sale (a little under even if accept Samsung's QLC, which is fine).
Prior to 2011 the trend was for GB/dollar to double very 14 months. (source mkomo.com/cost-per-gigabyte)
Post 2011 the trend is for GB/dollar to double every... 10 years maybe.
The HDD market went to shit due to mergers and price-fixing.
