How old are the disks in your NAS? (lemmy.fwgx.uk)

I have a ZFS RAIDZ2 array made of 6x 2TB disks with power on hours between 40,000 and 70,000. This is used just for data storage of photos and videos, not OS drives. Part of me is a bit concerned at those hours considering they're a right old mix of desktop drives and old WD reds. I keep them on 24/7 so they're not too stressed in terms of power cycles bit they have in the past been through a few RAID5 rebuilds.

Considering swapping to 2x 'refurbed' 12TB enterprise drives and running ZFS RAIDZ1. So even though they'd have a decent amount of hours on them, they'd be better quality drives and fewer disks means less change of any one failing (I have good backups).

The next time I have one of my current drives die I'm not feeling like staying with my current setup is worth it, so may as well change over now before it happens?

Also the 6x disks I have at the moment are really crammed in to my case in a hideous way, so from an aesthetic POV (not that I can actually seeing the solid case in a rack in the garage),it'll be nicer.

6 years old and running perfectly fine.

I have 5 WD RED disks in a RAIDZ1 config. In the first year I was experimenting with the sleep or spindown options. Then I have read that drives live longer if they run constantly. Now they are spinning 24/7.

The additional SSD has broken and been replaced 2x during these years.

Yeah flat out spinning is definitely better for reliability.
