1TB Camera Plus microSDXC

This 1TB microSDXC card carries UHS-I, U3, Class 10 and A1 ratings for sustained performance. It targets users who need high-capacity storage for 4K video recording in action cameras, drones or smartphones. The bundled SD adapter lets it slot into full-size card readers or laptop slots.

Sustained 4K capture

Sequential reads reach up to 150MB/s while writes hold up to 120MB/s, keeping bit-rates steady during long clips. The A1 rating means random I/O stays responsive when apps run directly from the card. U3 and Class 10 guarantee a 10MB/s minimum write floor so frame drops stay rare.

Drop-in install, watch the slot

Insert the card, format in the host device and record; no drivers or firmware steps are required. The adapter adds a mechanical joint that can loosen if the device vibrates heavily. The card itself is waterproof, shockproof, temperature-proof and X-ray proof, but the adapter is not rated for those extremes.

Questions about this item

How much power does the 1TB microSDXC card draw during all-day 4K recording?

The card operates on the host device's power supply; typical microSDXC UHS-I cards consume only milliwatts during sustained 120MB/s writes, so battery impact is minimal.

What adapter is required to use this microSDXC card in a full-size SD slot?

A microSD-to-SD adapter is included in the package, allowing direct use in laptops, cameras, or card readers with standard SD slots.

Will the UHS-I 150MB/s card work reliably in an older camera that only supports Class 10?

Yes, the card is backward compatible with Class 10 and UHS-I hosts; it will operate at the host's maximum supported speed.
