Questions about this item

Does the package include the microSDXC card and the SD adapter, or must the adapter be purchased separately?

The listing states "With Adapter", so the 512GB microSDXC card and a full-size SD adapter are supplied together in one pack.

Which capacity from the 64GB, 128GB, 256GB, 400GB, 512GB and 1TB range should I choose for 4K video and heavy app use?

The 512GB model provides the stated 170MB/s read and 90MB/s write speeds with U3, V30 and A2 ratings, giving ample space and sustained performance for 4K recording and app workloads.

What does the 170MB/s read speed mean when I move files to my computer?

At up to 170MB/s you can offload roughly 24GB — about 1000 high-resolution photos plus 30 minutes of 4K footage — in under three minutes with a compatible UHS-I reader.
