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.

Came across this article on TechRadar and it caught my attention. Especially the following, “The ten-disk hard drive, which is based on shingled magnetic recording (SMR) technology”.

My understanding is that SMR drives are not all that good for RAID setups. So I’m curious as to why this type of drive would be a good candidate for data centers. Thoughts?

They're HM-SMR (Host Managed-SMR) that requires specialized hardware and software. Which is why the article clearly states they're not for home users.

Read this and link about why Dropbox and other cloud providers are using them and HM-SMR is the future for larger hard drives.

So the history made full circle right to ST interface times.

Will wait until they invent IDE concept again.

Your understanding is incorrect. Only DMSMR drives are not very good because the disk is managing zones like a black box. HMSMR are great because user have full control on how to write data, thus eliminating all the shortcomings.
