I also have had a backup strategy since before using SSD since HDDs can, and have,
also died without warning. I backup to a RAID NAS.
Ditto. The Raid has saved me several times from failing Seagate disks
(now replaced with Western Digital).
FWIW, my VMs are resident in my $HOME directory and they do benefit
from being on the
SSD.
I recently replaced my 1TB /home drive with a 2TB unit, and decided to
move my QCOW VM drive from /home to a raw Windows partition on the old
drive. It made a huge difference and the VM now runs games at close to
native speed. Clearly an SSD would also have improved things but on
balance I think it was the right decision. A lot depends on what your
goals are and where you're starting from.
BTW, most people are probably using Sata-type SSDs, however my son
recently built a new machine with a 128GB Samsung PCIe NVMe as the
system drive (he's an animator and needs the speed). It's at least
twice as fast as a Sata SSD but of course you need a fairly new
motherboard to support it.
