Lexar ARMOR GOLD 1TB SDXC UHS-II V60

4.5

$209.9as of Jun 7

The Lexar ARMOR GOLD 1TB is the toughest 1TB SD card here, built from stainless steel with IP68 sealing and a 5m drop rating. It backs that durability with strong UHS-II speeds rated to 280MB/s read and 205MB/s write and a V60 class for 4K/60p video. The compromises are V60 rather than V90 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
