I have a couple of Linux systems that are on spinning disks... and I cannot convey how incredibly slow they are at "basic" tasks like system updates.
It's "just leave it running" levels of slow, in a world where I've got used to not leaving things like that because the context switching isn't worth it.
[there is zero reason for these systems to have "good" root storage, they're off-site backup nodes, and have decent big storage instead]
