Integral Micro SD Memory Card - 128GB - V30

U3 refers to the UHS Speed Class, indicating a minimum sequential write speed of 30 MB/s. V30 refers to the Video Speed Class, also guaranteeing a minimum sequential write speed of 30 MB/s, specifically optimized for video recording applications.

Yes, this microSDXC card is compatible with most modern smartphones and tablets that have a microSD card slot and support the microSDXC standard.

A1 certification means the card is optimized for running mobile apps, providing a minimum of 1500 IOPS (Input/Output Operations Per Second) for random reads and 500 IOPS for random writes. This leads to faster app launching and smoother performance when apps are stored on the card.

The V30 rating makes it suitable for recording 4K video, which is often required by dashcams and some security cameras. However, continuous 24/7 recording can put a strain on any card; check the camera manufacturer's recommendations for card longevity.

The card is designed to be water-resistant, but it's always best to dry it thoroughly before attempting to use it. Ensure all ports are completely dry. If any doubt exists, do not attempt to use it until professionally inspected or if data loss is not critical.

This Integral microSD card comes with a 5-year warranty.

Yes, the V30 rating and 100 MB/s read speed make it suitable for recording 4K video from drones. Ensure your drone's specifications recommend a card with similar speed and capacity.

Ensure the card is inserted correctly. Try cleaning the gold contacts gently with a dry, lint-free cloth. Format the card in a computer (backing up data first if possible) and then try re-inserting it into the device. Check device compatibility.

Verify the card is being used in a UHS-I compatible slot. Speeds are dependent on the host device; test the card in a different compatible device if possible. Ensure the device's firmware is up to date. Avoid running multiple demanding applications simultaneously.

Avoid removing the card while data is being written. Use the 'safely remove' or 'eject' function before removal. Run disk error checking tools on a computer. If issues persist, back up any recoverable data and consider reformatting the card.

Try formatting the card using a computer's disk management tools rather than the device's built-in formatting. Ensure the card is not write-protected (if it's in an SD adapter, check the physical lock switch). If formatting fails repeatedly, the card may be damaged.
