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.

About 10k power on hours. That's honestly a little surprising since I've had them for 7 years or so, but it's only been on 24/7 for the last year or two (used to just turn on when watching a movie or something).

From those hours, I should expect a few more trouble free years.

My OS drive is >30k hours since it used to be my desktop boot drive (tiny 120GB SATA SSD). I've been thinking about upgrading to NVME, since my desktop NVME is getting a little full (500GB), and it could also make for a nice cache. It's nowhere near dying though, with ~16TBW, so I'm in no hurry.
