Seriously.
Back to topic:
Badblocks on the WD Green AV HD has reached 13.60% completion with (0/0/0 errors) in 15:59:30. :-(
Yes, it is very slow to run.
Less than 1%/hour, apparently. That's a 2T drive, isn't it?
${DEITY} help us when we have to check out the half dozen or so 4T drives for a RAID array!
I'm back to thinking that a RAID array, a HIGHLY redundant, HIGHLY striped, full 64-bit wide+Hamming dual error detection, (72,64) of smaller drives, say 350G, might make more sense. What? Failure rates? Oh, right, yes.
Now THIS is interesting https://www.backblaze.com/blog/hard-drive-failure-rates-q2-2016/ https://www.backblaze.com/blog/hard-drive-failure-stats-q2-2017/ There seem to be some reliable 4T drives out there and the trend with 8T is looking good. Still, a RAID6 with 8T drives is a bit large for a home setting :-)
Really interesting links, thanks. My prejudice is to never buy WDC or Seagate and to buy HGST when I can, so it's good to have some confirmation.

I have a colleague/developer whose home system is set up to run continuous backup of him /home-equivalent (he's a Windows user and I'm not sure what the terminology is) to a USB portable drive-of-notable-size for each of his machines. He told me once that the 'backup' drives were less reliable than his main drive!
I found that ironic. He couldn't understand why I was laughing.
