Dash-cam and surveillance card

The SanDisk High Endurance microSDXC card is built for continuous recording in dash cams and home monitoring systems. Its microSD form factor with included adapter fits standard slots in cameras and readers. The card targets users who need reliable, long-duration capture rather than burst-speed photography.

256 GB capacity with U3 V30 sustained write

Rated Class 10, U3 and V30, the card guarantees a minimum write speed of 30 MB/s, reaching up to 40 MB/s. That headroom handles Full HD 1920x1080 and 4K UHD 3840x2160 streams without dropped frames. Read speeds up to 100 MB/s move footage off the card quickly. The 256 GB model is rated for up to 20,000 hours of recording; heavier bit-rates or higher resolutions will reduce that window.

Rugged build tested for temperature, water.

SanDisk validates the card against harsh conditions: temperature-proof, waterproof, shockproof and x-ray-proof. That resilience suits windscreen-mounted cameras baking in summer or freezing in winter, and outdoor security units exposed to weather. The bundled adapter lets you slot the microSD into full-size SD readers for desktop ingest without a dedicated microSD slot.

Soalan tentang produk ini

Will the 100MB/s read speed of this U3 V30 card work properly in an older dash cam that only supports Class 10?

Yes, the card is rated Class 10, U3 and V30, so it will fall back to Class 10 speeds in older devices while still providing the 40MB/s minimum write speed needed for Full HD recording.

How can I confirm the card is delivering the rated V30 performance after installing it in my security camera?

Check that the camera records 4K UHD (3840x2160) or Full HD (1920x1080) without dropped frames, and verify sustained write speeds of at least 30MB/s using a PC benchmark tool if needed.

Does the package include the SD adapter shown in the title, or do I need to buy one separately for my card reader?

The supplier title confirms an adapter is included, so you can use the microSDXC card directly in full-size SD slots without an extra purchase.
