Questions about this item

How fast will the 200 MB/s read speed actually move files off the card?

Real-world offload speeds reach the rated 200 MB/s when the card is paired with a UHS-I reader that supports that throughput, such as the SanDisk Professional PRO-READER; slower readers will cap the transfer below the headline figure.

What does the UHS-I U3 V30 rating guarantee for 4K video recording?

UHS-I is the bus interface, while U3 and V30 both certify a minimum sustained write of 30 MB/s, which is the threshold required for reliable 4K UHD capture on this card.

Will this microSDXC card fit my device that takes full-size SD cards?

Yes, the package includes a microSD-to-SD adapter so the 64 GB card can be used in standard SD slots as well as native microSD slots.
