850 evo POR SMART

Hey guys, we have had some power issues here in town and my evo has a POR of 4. Is this bad?, Is a sudden power loss devastating to the SSD or is it more of a data issue?

Thanks🙂

Yes and no?
I mean, it would be preferable to have a POR of 0 instead of 4 but 4 is still pretty low (unless you've just recently installed it).
Power loss may cause drives to stop working entirely but I don't know if that's very common nowadays, at least they dont seem as prone to it as old SandForce drives could be.
It's more likely to cause some data loss since it probably discards newly written data in order to protect the drive from failure.

Here's some information on how Samsung client drives handle power loss:
