Speed isn’t much of a concern as read/write will be limited to my internet connection.
They’ve apparently been running near 24/7 as they are only about 960 days old but have 833 days of runtime.
That being said, they will be in a zfs mirror and the data is not critical.
I’m aware that Seagate sux, but apparently WD’s 2.5" externals have the USB controller built into the drive, so they cannot be shucked.
As for your WD sux comment, “I reject your reality and substitute my own”, I’ve got a WD drive in my server at over 98,000 POH and Hard Disk Sentinel reports it as “perfect health.”
Also, you forgot Fujitsu.
I received a partial refund (enough that I’m willing to ‘risk’ using the drives)
