Questions about this item

Will the 80 MB/s write speed keep up with 4K V30 recording during long sessions?

Yes, the V30 rating guarantees a minimum 30 MB/s sustained write, so the 80 MB/s peak write speed handles continuous 4K UHD capture without dropping frames.

Does the card run hot or draw extra power when used all day in a camera?

The microSDXC card has no moving parts and draws minimal power from the host slot; it stays cool during extended 4K or 5K recording sessions.

What adapter or reader do I need to reach the 170 MB/s read speed on my laptop?

A UHS-I SD card reader or the included microSD-to-SD adapter in a UHS-I slot is required; USB 2.0 readers will bottleneck the transfer rate.
