As soon as I saw that this card was announced on the various tech sites out there, I knew that I had to buy one.  I went to Amazon and picked one up for $120.  This is a steep price compared to 64gb cards, but this is the largest capacity commercially available.  And I don't want to be swapping out micro SD cards.  That is just so inconvenient.  I did various speed tests on this card and can confirm that you can get 30MB/s+ read speed.  Fastest I saw was a little over 40MB/s.  Write speed varied greatly and seemed to decrease the larger the file got.  Minimum write speed i saw was just under 10 MB/s.  I use this on my Samsung Galaxy Note 3 and have not have any issues with it.
