I didn't find any 1TB M.2 cards yet. http://www.amazon.com/Samsung-850-EVO-250-MZ-N5E250BW/dp/B00TGIVZTW/ was 500GB but didn't fine 1TB.
This is not your everyday HDD form factor, it's not even mSATA it's the new M.2 form.
we have new HP Elitebook Folio 1040 G2 and I would like to upgrade the Hard Drive to 1TB but I couldn't see where the hard Drive is placed , please assist .
