Capacity & Format

This SanDisk Extreme microSDXC card delivers 64 GB of removable storage in the compact microSD form factor. It is built for action cameras, drones, smartphones and other portable devices that require high-capacity media in a tiny footprint. The UHS-I interface enables fast data transfer for demanding workflows.

Speed Fit

The card sustains a minimum write speed of 30 MB/s (V30) and reaches up to 160 MB/s read, making it suitable for 4K video capture and burst photography. Users who need sustained write rates above 30 MB/s or capacities beyond 512 GB should consider higher-tier options.

Deciding Spec

The V30 video speed class guarantees 30 MB/s minimum sequential write performance, which is the single figure that determines whether the card can reliably record your intended 4K footage without dropped frames.

Questions about this item

How do I confirm the card is delivering the rated 160 MB/s read and 60 MB/s write after setup?

Run a benchmark tool such as CrystalDiskMark or Blackmagic Disk Speed Test on a UHS-I reader; sequential read should approach 160 MB/s and write should reach at least 60 MB/s, matching the U3 and V30 ratings.

What comes in the package and is an SD adapter included?

The package contains the 64 GB microSDXC card only; the supplier title specifies "w/out Adapter", so a microSD-to-SD adapter must be purchased separately if your device needs full-size SD.

Should I choose this 64 GB model or a larger capacity for 4K video recording?

This 64 GB card sustains 30 MB/s minimum write (V30), suitable for 4K; larger capacities up to 512 GB in the same Extreme line offer identical speed ratings with more recording time.
