256 GB microSDXC for continuous recording

The SanDisk High Endurance microSDXC card delivers 256 GB of storage built for dash cams, home monitoring and security systems. It is rated Class 10, U3 and V30 to sustain Full HD and 4K video capture without dropped frames. The bundled SD adapter lets you move the card between microSD and full-size SD slots.

20 000 hours of sustained write endurance

The card is engineered to withstand up to 20 000 hours of continuous writing and rewriting, far exceeding the demands of typical burst shooting. Its 40 MB/s sequential write speed maintains steady throughput during long recording sessions. Read speeds reach 100 MB/s so footage offloads quickly when the card is full.

Temperature, water, shock and X-ray proof

The ruggedised construction protects stored data against extreme temperatures, immersion, physical impact and airport security scanners. This resilience means the card survives daily vibration in a vehicle mount or outdoor housing. The included SD adapter adds mechanical convenience without reducing the card’s protective rating.

Perguntas sobre este artigo

How much power does the SDSQQNR-256G-AN6IA draw when a dash cam writes to it continuously?

The card is rated for up to 20,000 hours of continuous recording, so it is designed to handle sustained write workloads without overheating or excessive power draw.

What host device or adapter must I already have to use this 256 GB microSDXC card?

You need a device with a microSDXC slot that supports UHS-I, or the included SD adapter for full-size SD slots.

Will this U3 V30 card work reliably in an older dash cam that only specifies Class 10?

Yes, the card carries Class 10, U3 and V30 ratings, so it is backward compatible with devices that require only Class 10 performance.
