When looking at Seagate’s description of the HAMR technology they state that “Each bit is heated and cools down in a nanosecond, so the HAMR laser has no impact at all on drive temperature, or on the temperature, stability, or reliability of the media overall” but I’m left wondering if I buy these drives as used when they get dumped after their 5 year enterprise life cycle then how much faith can I place on the “stability, or reliability of the media overall” after all that repeated heating? I’d be somewhat expecting more and more bad blocks to be cropping up with repeated use assuming it actually does degrade although I guess you could cope with it if you run something like ZFS Raid-Z2/Z3 stripes to deal with any problems as they occur.
