And it generally lowers longevity if disks are slept and woken up constantly.

  I have found that a 30 to 60 minute sleep time-out provides the perfect balance for infrequently used disks in terms of silence/power savings and longevity. Interestingly, one of my wireless routers with a USB port had a bug, and allowed a disk to sleep and cause it to wake afterwards. This made the disk overflow its SMART start/stop counter (so it's >65536, possibly double that number), yet the disk is still working at full performance to this day, and shows no performance degradation either. It's a Seagate notebook hard drive converted to an external drive (Seagate Expansion Portable, or something like that).

    I remember having bad experience once one of our guys decided "hey, it's backup server, we can just put some of the greens in it, backups are run all in bulk right?". Think 2/3 out of them died in a year, we preemptively replaced the rest.

      Greens are not designed for that kind of duty. Also they have variable speed spindles and variable speed seek to keep noise down. My parents' PC has a 1.5TB Green for backups for almost a decade now, and that drive is fine, too. Looks like it's mostly a horses for courses matter.
