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 was just looking at some 4tb refurb drives... and wondered the same.. i mean 50 euro is nothing but if it start giving me smart errors in a month i'd rather not
return it, recertified drives should be way cheaper (I recently bought a 14tb recertified with 5 year warranty from goharddrives for $115) and even then I wouldn't buy recertified drives unless it's from reputable sellers with warranties like serverpartdeals/goharddrive
I buy manufacturer-refurbished drives from serverpartsdeal, but would never trust a used drive from Amazon.
