Questions about this item

What does the 100 MB/s read speed mean for everyday recording?

The 100 MB/s read speed lets you offload Full HD and 4K footage to a computer quickly, cutting wait time after a long dash-cam or security-camera session.

How does the UHS-I U3 V30 rating affect real-world write performance?

UHS-I U3 V30 guarantees a minimum sustained write of 30 MB/s, so the card keeps up with continuous 4K video without dropped frames.

What does the card need to fit in a standard SD slot?

The microSDXC card ships with a full-size SD adapter; insert the micro card into the adapter, then slide the adapter into any SD slot.
