£99.95
The VIOFO 256GB industrial-grade microSD card is rated U3, A2 and V30 for sustained video recording, with environmental protection designed for repeated use in a vehicle.
Use in VIOFO dash cams that support this card capacity. The camera's own maximum-capacity limit still applies.
Dash cams repeatedly overwrite the card for hours at a time. VIOFO's industrial-grade card is designed around that sustained write workload rather than ordinary phone or camera use.
This 256GB card is rated for read speeds up to 100MB/s and write speeds up to 90MB/s, supporting the sustained data rates used by compatible VIOFO dash cams.
The card has an operating range from -25°C to 85°C, with waterproof, X-ray-resistant and antimagnetic protection for demanding in-car use.
Recording time depends on camera model, channel count, resolution and bitrate, so there is no single hours figure for every installation. Higher capacities preserve a longer history before the oldest unlocked files are overwritten.
VIOFO's official guide covers formatting a microSD card for dash-cam use and the maintenance routine recommended for reliable loop recording.
Dash cams write continuously and repeatedly, which is a much heavier workload than occasional phone or camera storage. Cards designed for sustained recording are better suited to that cycle.
No. Maximum supported capacity varies by camera model. Check the camera specification before choosing the card size.
Yes. Format the card using the camera's own format function before first use and periodically thereafter, following the camera manual.
