Lexar Professional SILVER PLUS microSDXC memory card 64GB

64 GB microSDXC for 4K capture

This Lexar Professional SILVER PLUS card is a 64 GB microSDXC memory card rated V30 and UHS-I. It targets photographers and videographers who need reliable 4K 60 fps recording and fast offload speeds in drones, action cameras, handheld consoles or similar devices. The operating range spans -25 °C to 85 °C and storage range -40 °C to 85 °C. An SD adapter is included for broader slot compatibility.

UHS-I bus caps peak throughput

The UHS-I interface limits maximum bus bandwidth so sustained write tops out at 100 MB/s and read at 205 MB/s despite the V30 guarantee of 30 MB/s minimum sequential write. In practice the card cannot exceed the host controller's UHS-I ceiling, so devices limited to older SD specifications will see lower real-world throughput. Buyers who need sustained writes above 100 MB/s or read speeds beyond 205 MB/s must choose a faster bus standard.

Step up from slower Class 10 or V10 cards

Replacing a Class 10 or V10 microSD card with this V30 model removes the bottleneck that causes dropped frames during 4K 60 fps capture. The jump is worth it when the host device supports UHS-I and the workflow demands consistent 100 MB/s write performance. Users staying with Full HD 30 fps or lower bit-rates will not see a practical benefit over cheaper lower-tier cards.
