Overview
A 2 pack of 64GB microSDXC cards rated UHS-I, U3, A1 and V30, with an SD adapter included, built for security cameras, dash cams, gaming consoles, and phones or tablets that need sustained 4K recording.
Lexar backs the card itself with a 10 year warranty, though the included adapter carries only one year.
- 64GB microSDXC, sold as a 2 pack
- UHS-I, U3, V30 and A1 rated

Who it's for

Performance notes
Lexar rates the card at up to 100MB/s with a V30 sustained write speed for 4K video and an A1 rating for running apps from the card. At 64GB, Lexar estimates roughly 3 hours of 4K footage or 10 hours of 1080p, about 18,800 photos, or 9,900 songs, though actual usable capacity runs somewhat below the labeled size once system files are accounted for.
