A lot of "too sleep or shut down" resurrected questions lately. How about this one? Years ago it was rumored spinning down was bad for hard disk head's. Of course there would be the obvious energy being wasted keeping them spinning all the time. I've been looking around to see if there's been any new opinions or new technologies that have changed. Obviously I'm talking about HDD's (not SSD's). Would it the opinion be the same for single versus RAID disks? I have a 2 drive RAID 0.
