The NV Cache option eliminates the need for a battery on the raid controller (which has an average lifespan of ~3 yrs and runs over US$100 usually). It doesn't affect anything other than that.
Hi all, I've been trying to research whether the Flash Backed Cache on my PERC H710 RAID controller will make a write hole impossible or just unlikely.  Does any one know? Many thanks, Andrew
Does a Flash Backed Cache make a RAID 5 write hole impossible, if not how 
unlikely is it?
