Although with an Xbench score of 33.42 is not quite as fast as eg. the sauschnelle 64GB Transcend SDXC 300x (Xbench score 45.92), but almost just as fast as the boastful 64GB SDXC 600x of Komputerbay (Xbench score 33.93) - and even again clearly cheaper and higher quality in appearance. Fats surprise: The Savetech writes even the extremely demanding 200Mbps All-Intra mode of GH4 so far without complaint. Even after 3h endurance test (ie precisely 6x 30 min ...) any typographical errors (!) And that's where Panasonic for GH4 actually super current UHS-1 U3 (= Class 3) prescribes SDXC's ... Chapeau!
