64GB microSDXC with A1 app rating

The Patriot EP Series card delivers 64GB of storage in a microSDXC form factor. It carries UHS-I, U3, Class 10, V30 and A1 ratings for broad device compatibility. Read speeds reach up to 100MB/s and write speeds up to 80MB/s. An SD adapter is included for use in full-size slots.

Ideal for Android phones and 4K cameras

This card suits users who want to install and run apps directly on external storage thanks to the A1 classification. It also handles continuous 4K video capture with its V30 sustained write rating. Buyers who need more capacity should consider the 256GB variant in the same series. Those requiring UHS-II or higher sustained write speeds should look elsewhere.

64GB capacity with 4K headroom

The 64GB capacity holds hours of 4K footage or thousands of high-resolution photos before filling. Sequential read performance up to 100MB/s speeds up file offloads to a computer. Write performance up to 80MB/s keeps pace with demanding video bitrates. Intensive workloads exceeding 80MB/s sustained write will saturate the card.

Questions about this item

What device slot is needed to use the 64GB microSDXC card?

A microSDXC slot is required; the included SD adapter lets you use it in full-size SD slots.

Will the U3 and V30 ratings still be met in an older UHS-I host?

Yes, the card runs at UHS-I speeds; U3 and V30 minimums are maintained on any UHS-I device.

How can I confirm the A1 rating is working after setup?

Move apps to the card on Android; they should launch and run directly from the 64GB storage.
