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

    It’s unlikely any long term failure would be known this soon. Which is why you don’t see stats.

    There’s nothing like the SanDisk SSD failure debacle, at least, known in the community.
