I bought 4 WD Red 1TB drives about a month ago and built a FreeNAS box around them.
After burning them in, they had a load cycle count (S.M.A.R.T. attribute 193) of about 100 (101, 105, 106, 90).
It's been a few weeks and the box has spent most of that time off. I turn it on for a day every few days and back up to it, then I shut it off. The backups happen twice a day, 12 hours apart.
I ran a smart command to check the parameters on the drives out of curiosity. In 2 week's time, the drives have jumped to almost 700! Clearly these drives are parking the heads far more often than I'd like them to.
I searched around, and found a tool WD makes specifically for the WD Red drives that is supposed to lengthen the wait time before the heads park. Annoyingly, the tool doesn't tell you what the current timeout is, or what it is lengthened to. Nor does it let you specify a custom timeout.
I'm posting it here in case anybody else has WD Reds and is worried about the drives wearing themselves out.
