These drives went on sale so I decided to pick up one to expand my home lab storage capacity. After doing some research on the Red vs Black edition, I found a few posts that referenced head parking issues in the 4TB Red series that significantly reduce the drive’s lifespan.
Apparently you can run a utility against the drive to correct the issue with idle3 http://idle3-tools.sourceforge.net/
Before setting the idle timer to 0, I was getting 273 Head Parks/day. After the utility was run, I am now showing 0.67 Parks/day.
