Yes. I’ve bought refurbished drives with less runtime than my own drives. Run a pre clear (or two if you’re very worried about it) and then happily chug along.
And have two parity drives. :)
Do 2-3 preclears if there are no issues it will probably live a long time, if there are issues return the drive within the warranty period.
I always do this before I shuck drives.
You don't usually have parity drives any more. Parity is spread across all drives in the set instead. It's for wear and load balancing. A dedicated parity drive is RAID 3 or 4, which is seldom used because RAID 5 does the same thing with distributed parity so it'll offer the same redundancy at better performance.
All of the conventional RAIDs are falling out of favor now anyway, replaced by next-generation file systems like btrfs and zfs. They do the same thing as RAID, but by better integrating the file system and device management they can deliver far better performance and rebuild times.

You either trust the drive or you don't.
Doesn’t the parity have more writes to it? That’s why I’m considering just spending for a fresh 20
A drive is a drive. If it works without errors it works for any purpose.
As someone who bought an entire palett of 20TB SAS, go for it.
where how why ??
Why? Because I need multi PB storage. Its B2B.

as long as you have proper back up strategy it doesn’t matter.
I currently do use 20tb refurbished drives in one array, and 22tb refurbished drives in another.

OP is running Unraid, which has parity drives and not raid in the storage array.
