I decided to improve the data storage at home. I purchased four WD red drives, 2 TB each.
After reading up on all opinions on the net I'm unsure whether I should go for Z1 with three drives and keep one as a spare or do Z2 instead.
Pro Z1 - less power consumption, the spare drive will not wear.
Pro Z2 - more redundancy.
I do have backed up all my real important data on archive grade DVD's anyhow, and I keep doing it.
Thoughts?
