Don't mind the listing stating there's only 620GB of usable storage, I think someone might have lost a couple zeros when calculating that number.
Data Hoarder
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.
I wonder how they test as far as writes remaining. Those things have to be have been run hard.
Also, hope you have a friend with a pallet truck.
