There's so much insanely awesome tech in these drives. "12nm integrated controller" (meh ok). nanophotonic laser (fancy led?). photonic funnel. superlattice platinum-alloy media. plasmonic writer. quantum antenna. https://www.tomshardware.com/pc-components/hdds/new-hamr-las...
> In HAMR HDDs, the nanophotonic laser diode heats tiny portions of drive media to temperatures of 400°C ~ 450°C to reduce its magnetic coercivity before the plasmonic writer writes data to this area.
I get that it's a very very small area. I am curious though how power consumption compares!
It's crazy how far ahead Seagate has gotten. WD and Toshiba haven't been making anywhere near the progress, it feels like. Exos drives are crazy high performance and stunningly affordable.
