News Exclusive: Microsoft’s New Surfaces Use Toshiba’s Tiny BG4 SSD

Yeah so who's going to pry apart their new Surface to upgrade the SSD? Anyone?

Nope didn't think so. I have a failed Surface Book that is in 900 pieces in order to get the SSD out of that. That thing aint ever working again.
 
I'll have to check when I get home, but I think my new Dell XPS 15 laptop comes with this kind of SSD. It's a 256gb, which I promptly swapped out for a 1tb ssd.
