With the suggested adapter why not using a standard 2.5'' sata disk?
Sata for OS should be enough, no need for an ssd
At the time, the smallest SSDs were about half the price of the
smallest HDDs. My Ceph nodes are only using ~4GB on /, so small and
cheap is fine. I would've continued using the USB pen drives if they
hadn't caused so many problems.
It only while composing my email that it occurred to me that the SSD
mirrors might fail the same way as the USB drives. I'm less worried
about it, but I do plan to monitor their wear levels now that I has
occurred to me.
The SSD failures I've seen have all been firmware bugs rather than flash
wearout. This has the effect that a RAID1 pair are likley to fail at the
same time!
