Buyers who require an SD adapter for a laptop slot or camera should look at a different bundle. Anyone needing faster write performance for 4K capture will need a higher speed class.

The Speed Class 10 and UHS Speed Class U1 markings guarantee sustained write performance suitable for 1080p recording. A1 qualification means the cards can run apps smoothly on supported Android devices. Verify that your device supports microSDXC before purchase.

Questions about this item

Does the 2-pack include the 64 GB microSDXC cards only, or does it also come with a full-size SD adapter?

The retail pack contains two 64 GB microSDXC Class 10 cards and no adapter is included.

The listing mentions Class 10, U1 and A1 ratings — which one should I rely on for smooth app performance on my Android phone?

The A1 rating guarantees minimum random read and write speeds for app loading, while U1 and Class 10 both certify 10 MB/s sustained write for Full HD video.

The card advertises up to 100 MB/s read speed — will I actually see that when copying 1080p footage to my laptop?

Real-world transfer rates depend on your card reader and USB port, but the 100 MB/s figure is the maximum sequential read speed the card can deliver under ideal conditions.
