VIOFO 256GB Industrial Grade microSD Card, U3 A2 V30 High Speed Memory Card with Adapter, Support Ultra HD 4K Video Recording

The VIOFO 256GB industrial-grade card is purpose-built for continuous loop recording in dash cams, security cameras, and other devices that write data 24/7. The industrial endurance rating handles the sustained write cycles that consumer-grade cards fail under within months of dash cam use.

The U3 A2 V30 rating guarantees minimum 30MB/s write speed — sufficient for reliable 4K video recording without dropped frames or write errors under continuous use. VIOFO's branded card ensures compatibility testing with their dash cam models.

Industrial endurance cards cost more than consumer cards at the same capacity — the premium is justified specifically for continuous-write applications like dash cams. For occasional-use devices, a standard high-endurance card is adequate. The right storage for dash cam owners running 4K or multi-channel systems who have experienced consumer card failures and want purpose-built industrial endurance for reliable long-term operation.
