Questions about this item

How long will the 170MB/s read speed hold up during a long 4K video capture?

The card is rated U3 and V30, guaranteeing a minimum 30MB/s sustained write speed, so the 170MB/s read peak will not throttle during continuous recording.

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

Operating voltage is 2.7–3.6V with no moving parts, so heat and power draw stay minimal even during extended 360° camera or drone sessions.

My device only has a full-size SD slot — what adapter do I need?

You will need a microSD-to-SD adapter; the card itself is the 0.590 × 0.43 × 0.039 in microSDXC form factor.
