Ranked #3 in Best 1TB SD Cards

Lexar ARMOR GOLD 1TB SDXC UHS-II V60

4.2

3 sources1 derived$172as of Jul 1

Stainless steel construction, IP68 sealing and a 5m drop rating make the Lexar ARMOR GOLD 1TB the toughest 1TB SD card on this list. Speed keeps up too: rated 280MB/s read and 205MB/s write over UHS-II, with a V60 class that covers 4K/60p video. The compromises are that V60 rather than V90 rating, and measured writes that can fall below the headline figure.

Strengths

— Stainless-steel monolithic construction rated to survive 5m drops and 370 Newtons of pressure
— IP68 dust and water resistance, among the toughest SD cards available
— Strong UHS-II speeds rated up to 280MB/s read and 205MB/s write

Watch-outs

— Measured write speed in some tests lands well below the rated maximum
— V60 rather than V90, so less headroom than the ProGrade for the highest bitrates
— Needs UHS-II hardware to hit full speed
