Lexar Professional SILVER PRO 1TB SDXC UHS-II V60

4.7

3 sources1 derived$499.99as of Aug 1

The Lexar Professional SILVER PRO 1TB is the value pick of the UHS-II group, giving you genuine UHS-II speed at an affordable price. It is rated up to 280MB/s read with a V60 class for 4K/60p video, and reviewers rated its performance highly for the money. The compromises: a slower rated write than pricier cards, and a standard, non-rugged build.

Strengths

— Excellent value, delivering UHS-II speed at a noticeably lower price than flagship cards
— Rated up to 280MB/s read for fast offloading of large files
— V60 class supports 4K/60p video recording

Watch-outs

— Rated 160MB/s write trails the faster V60 and V90 cards here
— V60 rather than V90 limits the highest-bitrate headroom
— Standard plastic build lacks the ARMOR GOLD's extreme ruggedness
