Capacity and speed ratings

This SanDisk Extreme microSD UHS-I card provides 64GB of storage with a maximum read speed of 170MB/s and a maximum write speed of 80MB/s. It carries UHS Speed Class 3 and Video Speed Class 30 ratings for sustained capture. The bundle includes the card and an adapter for full-size SD slots.

Ideal for action cameras and mobile devices

Photographers and videographers recording 4K UHD or 5K point-of-view footage will benefit from the V30 guarantee. The A2 rating also helps Android devices and handheld consoles load apps faster. Buyers who need more storage should consider higher-capacity models.

Write speed determines suitability

The 80MB/s write limit is the single figure that decides if this card matches your workflow. It meets the V30 threshold for 4K UHD but may not sustain higher-bitrate modes that demand faster sequential writes. Check your device's required write speed before buying.

Questions about this item

How can I verify the card is delivering the 170MB/s read and 80MB/s write speeds after setup?

Run a benchmark tool such as CrystalDiskMark or Blackmagic Disk Speed Test on a UHS-I reader; sequential results should approach 170MB/s read and 80MB/s write for this 64GB model.

What does the bundle include and what must I buy separately?

The bundle provides the 64GB microSD card and a full-size SD adapter; a UHS-I compatible card reader is not included and must be purchased separately.

Which capacity should I choose between 64GB, 128GB, 256GB, 512GB and 1TB?

The 64GB card offers 170MB/s read and 80MB/s write; 128GB reaches 245MB/s read and 120MB/s write; 256GB, 512GB and 1TB hit 245MB/s read and 170MB/s write — pick the smallest capacity that holds your footage.
