Western Digital WD Red 1 TB Actual User Experience?

I am not worried, my point was that I had two identical arrays (until I replaced the two Seagates in the primary with two WD Red label drives) and one has an LCC count in the mid 30's and the other has an LCC count of almost 800), this fact at first surprised me and then I realized the difference was that I had drive spin down enabled on the backup unit since it was only active about 4 hours of the day and not on the primary since it is active most of the day. I initially had it set on both arrays, but the delay in loading files was aggravating.
