You are wrong, its not cause by computer OS...
If you read my post again more carefully you'll notice that I was specifically responding to a post by
ds256, where it was very obvious that it was his PC that woke the disks up at that point. So no I wasn't wrong, in that moment it was the PC accessing the NAS that spun his disks up. So all the devices on your network accessing the NAS without you knowing it is another can of worms for you spindown guys to deal with even if you could have the Qnap to not access it's disks...
...because this crappy chinese NAS Qnap wake up my HDD from sleep even when I unplug LAN cable from it!
And you're sure that the missing LAN doesn't cause spinups by itself? Like for example writing regularly in the logs (placed on disk) about the major error condition (and all the things failing from it) that you've caused yourself by pulling the cable?
Anyway, as we've been over again and again with you and many other poeple that expect the spindown to work, there are far too many features in the QTS today that will spin drives up. Nobody in the community is in a postition to fix QTS so bring that up with Qnap instead.
LOL So stupid device, but probably create to kill faster people HDD's.
Apart from that being a stupid conspiracy theory it's also technically incorrect. It's not the spinups that will kill your disk.
You have a WD Red that is specified for a minimum of 600k load/unload cycles (pretty much the standard for all NAS disks today). Let's do the math with the increase of 12 LLCs per day that you reported here. 600000/(12*365.25)=136.89. So for the next 134 years there's no reason for you to worry about the disks being killed by spin-ups. I'm pretty sure the disk, the NAS and you are dead well before year 2154...
RAID have never ever been a replacement for backups. Without backups on a different system (preferably placed at another site), you will eventually lose data!
A non-RAID configuration (including RAID 0, which isn't really RAID) with a backup on a separate media protects your data far better than any RAID-volume without backup.
All data storage consists of both the primary storage and the backups. It's your money and your data, spend the storage budget wisely or pay with your data!
