This is why you gotta test your stashed drives yearly. This drive surface was already having issues after just one year

I use a few hundred drives as cold storage backup pools and I try to get to them twice a year but I always test them at least once a year. I lose 2-3 drives every year. Since they are mostly smaller 750GB to 4TB drives in 12x driver RAIDz2 pools it is not really that bad and I have never lost data yet.
What are you using for a server and how do you manage it? I need something at least 500+TB, but I've yet to find something that's reasonably cost effective and easy enough for a dumbass like me to manage (hardware more than software).
My average cost per usable TB is around $11 per TB, but most of my drives are smaller used SATA/SAS drives. My main pools come out to about 450TB of usable storage.
Edit, Copy paste from the post I never got around to making.
Main Pools 2023, are on 24/7/365 - 360-420 Watts.
I use 3 UPS units to protect them.

Main pool - 261.26TB, This is all 1 pool, but I broke it up on the list since I use 3 different drive sizes.
Total usable TB : 450.17TB
Total Cost : $4900 / 450.17TB = $10.89 per usable TB, not bad considering the amount of drives were purchased new.
