Thanks for having a look. Sure, we can do that, I have no particular attachment to doing it based on size (it's just the way it occured to me). I am curious, though: While regardless of size vs time based estimates, are the numbers expected to be similar for volatile regions? All these numbers being from nvdimm DSM docs.
Thanks, Davidlohr
