      Heat-Assisted Magnetic Recording. It uses a laser to heat the drive platter, allowing for higher areal density and increased capacity.

      I am ignorant on the CMR/SMR differences in performance

          My poor memory is telling me the heat is used to make the bits easier to flip, so you can use a weaker magnetic field that only affects a smaller area, allowing you to pack in bits more closely. It shouldn’t have the same problem as SMR.

          That sounds absolutely fine to me.

          Compared to an NVME SSD, which is what I have my OS and software installed on, every spinning disk drive is glacially slow. So it really doesn’t make much of a difference if my archive drive is a little bit slower at random R/W than it otherwise would be.

          In fact I wish tape drives weren’t so expensive because I’m pretty sure I’d rather have one of those.

          If you need high R/W performance and huge capacity at the same time (like for editing gigantic high resolution videos) you probably want some kind of RAID array.
