PLP is important on mostly Block Storage, Ceph should easily recover
from that situation.
That's why I don't understand why I should pay more for PLP and other
protections.
I'm no expert (or power user) al all, but my reasoning is: if something
power-related can take down one of my servers it can just as easily take
down *all* my ceph servers at once.
And that could just as easily render all three copies inacessible.
Plus how I understand it also: using SSDs with PLP also reduces latency,
as the SSDs don't need to flush after each write.
(but again: this i my understanding, and I am no expert on the subject)
