gernb1....there is no way of telling exactly what is taking place at moving data.

IMO....for now...it's comprised of similar component sets for typical  paging or shadowing processes,  combined with virtual mapped management. 

"What would you do with an extra 30 minutes of battery life on your laptop? The SSD's ultra-low power consumption gives you time to decide. In a typical scenario combining read/write, seek and standby, the SSD required roughly one-tenth the power of a hard drive. That means greater productivity and less aggravation for you."

 Adding 30 minutes time to my battery time(almost 2 hrs...lol) would not add much. When they state additional times of 5 hrs, then  I would say they moved from the virtual management to a  physical condition of management.
