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.

Do MAMR drives carry an early adopter risk relative to CMR drives? (alien.top)

I have a choice between two Toshiba HDDs: MG09ACA18TE and MG07ACA14TE. According to this datasheet, the first one is a 18TB Helium MAMR drive and the second is a 14TB Helium CMR drive.

The 18TB translates to a better $/TB where I live, which is the main reason why I was leaning towards it. Also, Toshiba claims that MAMR technology "has been tried and tested for many years".

Do you have any knowledge of or experience with MAMR? Is MAMR technology likely to be as reliable as CMR? Or should I get the CMR drive instead?

Thanks

Yeah, I read their report from Q3 2022. However, the problem is that they don't use any MAMR drives, which is a new technology, so that doesn't help me.

The helium aspect is what i was focused on. My bad.

That said, the HAMR vs MAMR thing I see as being sorted for the most part as the release of these types of drives to the enterprise market gives me assurance as to the durability of them. "new' only in that the drives have been somewhat recently come into the consumer arena.
