64GB microSDXC Card for Android

The SanDisk Ultra microSDXC card delivers 64GB of storage for Android smartphones and tablets. It carries UHS-I, U1, Class 10 and A1 speed ratings for reliable performance. Read speeds reach up to 100MB/s for quick file transfers. A standard SD adapter is included for broader device compatibility.

Ideal for Mobile Apps and Full HD Video

This card suits users who want faster app loading on Android devices thanks to the A1 rating. It also supports Full HD video recording and playback at Class 10 speeds. Buyers needing sustained write speeds for 4K video capture should consider cards with Video Speed Class ratings. Those requiring larger capacities can select higher-capacity models in the same range.

A1 Rating Enables Faster App Performance

The Application Performance Class 1 rating means the card meets minimum random read and write IOPS thresholds for smoother app operation. This specification distinguishes it from cards that only guarantee sequential speeds for media storage. Random I/O performance directly affects how quickly installed apps launch and run on a smartphone.

Questions about this item

What is included with the SanDisk Ultra microSDXC 64GB card and do I need to buy anything else to use it in a standard SD slot?

The card comes with an SD adapter so it can be used in full-size SD slots; no extra purchase is required for that purpose.

Should I choose this 64GB A1 UHS-I U1 Class 10 model or a different capacity for my Android phone?

This 64GB model carries the A1 rating for faster app loading and U1/Class 10 for Full HD video; pick a larger capacity only if you need more storage space.

What does the "up to 100MB/s" read speed mean when I am actually transferring photos or videos?

It indicates a maximum sequential read rate; real-world transfers of mixed files will be slower, though the card can move around 1000 photos in a minute under ideal conditions.
