As for a hardware problem, the drives were ones purchased in Lenovo
professional workstation laptops, and, while you do get lemons
occasionally, I tried 4 different ones of the exact same model and had the
exact same issues. Its highly unlikely I'd get 4 of the same brand to have
hardware issues. Once I went back to ext4 on those systems I could run the
devil out of them and not see any freezes under even heavy load, nor any
other hardware related items. In fact, the one I used at my last job was
given to me on my way out and it's now being used by my daughter. It's been
upgraded from Fedora 23 to 26 without a hitch. On ext4. Say what you
want, BTRFS is a very bad filesystem in my experience.
