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.

Look into the S.M.A.R.T. reports of each drive.

On Synology DSM 7.x: Storage Manager › HDD/SSD › Health Info › S.M.A.R.T. › S.M.A.R.T. Attribute › Details › Power_On_Hours

The power-on hours are shown directly on the Health Info page, no need to click through to the SMART attributes.
