Designed for Dash Cam Recording

This 256GB microSDXC card belongs to the Team Group Dash Card series and is built specifically for continuous video capture in dashboard cameras. It carries UHS-I, Class 10 and U1 speed ratings to sustain Full HD recording without dropped frames. The bundled adapter allows use in standard SD slots.

Sustained Write Performance for Long Drives

The card is tested for stable storage performance over long periods and continuous recording sessions typical of daily commuting. Its UHS-I U3 V30 specification supports a steady write throughput that keeps 1080p footage at 30fps smooth and uninterrupted. This consistency matters more than peak burst speed for loop recording.

Rugged Build With Included Adapter

The card endures operating temperatures from minus 25 to 85 degrees Celsius and is rated shockproof, waterproof and X-ray proof. These protections help preserve data if the camera suffers impact or exposure. The supplied SD adapter makes it simple to offload footage to a laptop or desktop card reader.

Questions about this item

Does the card generate noticeable heat or draw extra power during continuous 1080p dash-cam recording?

The card is rated for sustained Full HD 1080p capture at 30fps and operates reliably from -25°C to 85°C, so heat and power draw stay low even during all-day loop recording.

My dash cam only has a full-size SD slot — will the included adapter let this microSDXC card work immediately?

Yes, a full-size SD adapter is supplied in the box, letting you insert the 256GB microSDXC card directly into any standard SD slot without extra purchases.

Will this UHS-I U1 card keep up with an older dash cam that only supports Class 10 speeds?

The card carries Class 10 / U1 ratings, matching the older cam’s maximum write speed, so it records Full HD video smoothly without dropped frames.
