So is there a raid 12 for my 13 500GB drives?
Don't forget the power bill, even if they sit idle most of the time. 12 drives * 5 watts * 24 hours * 365.25 days ~= 525 kwh. That would cost me $157 aud a year for electricity.
If I instead bought a 6TB drive brand new I'd break even after 3 years, assuming the 500GB drives are $0.
Yeah, it's half joke, half backup territory (so the drives could just be offline mostly).
RAIDz2 for 5.5TB with 2-disk redundancy.
All of a sudden USB becomes important. ๐
