       | 28TB for $350, with a 6 month warranty, is wildly good.

       | 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-

       | 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.
