What kind of SSD for Raspberry Pi when using persistence? Sata, mSata or m.2?

I am not sure if I understand completely, so you choose old-fashioned HD because it is more reliable than SSD or because it is cheaper?

So I hope! (reliability)

@VioletAnt

Are you using persistence?

yes - MapDB and for some items RRD. But the main persistence is a MariaDB on my NAS.

@VioletAnt

Did you separate the logs and swapping files like mentioned in this post: Corrupt FileSystems every 2-3 month?

nope. I do backup regularly (only config, still trying to figure Amanda out!)=

@VioletAnt

Or is this separation not needed anymore with an old fashioned HD?

I don’t know…

@VioletAnt

Do you know what is the power consumption difference between a SSD and the old fashioned HD? Didn’t find anything conclusive…

hmm… I’m not sure, I think I read sometime ago, that for spinup the HD needs a bit more power, but in “real life” it wouldn’t make much difference?
My HD-housing came with an Y-cable so I have a seperate USB-Port just for power (I could also use some PIN with 5V power. But I already use a powered USB-Hub which works fine.

hope that helps…
