64 GB microSDXC for action cameras

The SanDisk Extreme microSDXC card delivers 64 GB of storage in the UHS-I format. Rated V30, U3 and A2, it sustains the write speeds required for 4K video capture and fast app loading. A full-size SD adapter is included for use in laptops and card readers.

Suited to drone and action-cam owners.

Creators recording 4K footage at high bitrates or running apps directly from the card will benefit from the 60 MB/s write ceiling and A2 random-performance rating. Users who need sustained write throughput above 60 MB/s or capacities beyond 64 GB should consider higher-tier media.

Handles 4K60 and app workloads.

Sequential reads reach 160 MB/s for quick offloads, while the 60 MB/s write limit comfortably covers 4K60 recording and A2-class app performance. Extended 8K capture or professional codecs demanding faster sustained writes will exceed the card's headroom.

Questions about this item

What host device slot is required for the UHS-I/U3 microSDXC card to deliver its rated speeds?

The host must provide a microSDXC UHS-I slot; the card is also compatible with microSDHC UHS-I slots but will operate at lower speeds there.

Will the bundled SD adapter let me use this card in a legacy camera that only accepts standard SD cards?

Yes, the included adapter converts the microSDXC form factor to full-size SD so the card fits older SD slots, though the camera must still support SDXC capacity and UHS-I for full performance.

How can I verify the card is sustaining V30 write performance after installation?

Record 4K video at the camera’s highest bit-rate; if the clip writes without dropped frames or buffer warnings, the card is meeting its 30 MB/s minimum sustained write speed.
