I don't think there are here people advising to use consumer grade
ssd's/nvme's. The enterprise ssd's often have more twpd, and are just stable
under high constant load.
My 1,5 year old sm863a still has 099 wearlevel and 097 poweronhours, some other
sm863a of 3,8 years has 099 wearlevel and 093 poweronhours.
When starting to use ceph try to keep your environment as simple as possible,
and as standard as possible. You need to be aware of quite some details if you
are trying to squeeze out the the last few % ceph can offer.
For instance disabling the ssd/hdd drive cache gives you better performance (I
do not really notice it, but that is probably because my cluster is having low
load)
Also realize from this page of Vitalif, at some point it will not become any
faster. I was also thinking of putting wal/db on ssd's for the hdd pool. But I
skipped it for now. The hdd pool is not fast, but I am also not complaining
about it.
This is my fio[1] and a micron sata ssd drive result[2]
