ZFS HDD Mirror read error for one of two HDDs

ZFS' regular activities probably prevent the automatic powerdown from kicking in.

Of course I'd still avoid those drives.
 
You can disable idle spin-down on the hard disk.
It's better to use HDD which are design for non-stop operations in datacenter like WD Gold.
 
I also discovered a 2-Bay Docking Station today with good reviews.
It seems to be powered externally which is actually good, and also has external cooling provided.
Kind of curious whether I should use RAID-1 (Mirroring) natively as that device supports it, and then on top use UFS as a filesystem or should I still resolve to software RAID with ZFS ?

Reading opinions in the internet people actually say that it is not good to have NAS HDDs in a PC which you frequently power off, and on due to heavy wearing.

I'm the guy that had to tell customers all their lives photographs are gone when they bring me their WD Passport to revive.

If you shop for disks by lowest price you will regret it. With both disks showing trouble I hope you see this. The "NAS-Line" is just marketing term for talking heads.
They are not Enterprise Drives. Two new disks failing is not surprising to me from Western Digital.

You are merrily mixing WD Passport (USB Consumer, WD Red (cheap NAS drives), WD Red Pro (OK quality NAS drives) with Enterprise class (WD Ultrastar, WD Gold). I agree that buying to cheap makes no sense.

But other than that, your hate for WD or anecdotal experience is clouding things. I have worked with hundreds of WD Enterprise drive and they have been overall very reliable, with issues usually showing up in SMART data well before a drive would fail. Not buying anything but WD here...

I used a dual-bay USB-C external HDD station for over a year no problem as a NAS with a laptop NTFS, ext4, ZFS, and briefly UFS. I'd use RAID1 with software raid or as-natively as ZFS can do it! I normally do single-drive and occasionally connect a 2nd disk for backup sync.

There's hdparm commands to disable HDD suspend/power-saving stuff at the firmware level (I set stuff years ago from Linux and it carried-over to Windows and FreeBSD)l; I had no problem with quick access from Linux and FreeBSD, but wasn't a fan of Windows having to spin-up first and delay GUI access (efficient but annoying :p)

I've done daily reboots most of that year no problem and had a few random power-offs no data loss or issue. Even had it fly off a table with a WD drive and still working months later :p
 
As others have suggested, a drive with 2232 power on hours is not expected to fail mysteriously (even if it has been power cycled often). A second drive doing the same thing is not likely to be a coincidence. Two drive failures point to something in the environment. You need a plan to test the components one at a time.

The idea with a second HDD and occasionally syncing is actually also not that bad eventually, because if the second HDD is not used, it would probably sustain longer, and if the first HDD breaks, the second one could be used until the first one gets replaced.
I am just wondering if I use one HDD or RAID with both HDDs and mount it/them on each boot to a directory then that would mean that they should actually not suspend, right ?
Especially NAS HDDs which should work 24/7.
Suspending means that on each wake up they need to spin up again which probably wouldn't be very good if happening frequently.

My typical use case is that I need a HDD to be available each boot as I frequently copy data over from HDD to RAM.
So, I am actually wondering which approach would be better.
1 HDD for continuous usage, and one for backing stuff up + an external backup on a external HDD ?
Or should I directly use 2 HDDs in a RAID 1 construct + keeping an external backup ?
Obviously if a HDD stores data, and doesn't spin up/down as often it should live longer, if I am not wrong.
Would be interesting to know which of the methods is actually the preferred one.
Space is not an issue as both have 12 TB.

I believe it is the motherboard, because I changed that some time ago, and then problems started with the HDDs.
Just to make sure I want to get a external 2-bay dock station and see whether those problems would return.

I checked SATA cables, too, but they acknowledge new drives, and I even tried new SATA cables on different connections, but same result.
Another part could be the PSU, but that is very unlikely, because if it would be faulted, I would have way more problems than just the HDDs.
