Thanks for posting your experiences here. This could be where the attempt to use less energy too aggressively ends up making the drives fail prematurely, and thus costing you more in the long run... I wonder if someone has done the math of the cost of failed drives versus money saved due to drives using less energy? How many load cycles are those drives quoted to be good for? As the revision '00P8B0' was the one quoted in the initial post's WDC / Synology links, I would appreciate any further reliability / problem feedback you have regarding using these drives in a RAID array.
