SanDisk Ultra SD Memory Card - 512GB

SDXC (Secure Digital eXtended Capacity) is a standard for SD memory cards that supports capacities larger than 32GB. Most modern devices with SD card slots are SDXC compatible. However, older devices only supporting SDHC or SD might not read SDXC cards. Always check your device's specifications.

UHS-I (Ultra High Speed I) is the first generation of the UHS bus interface, offering speeds typically up to 104 MB/s. UHS-II is a newer standard that uses an additional row of pins to achieve much higher speeds, often up to 312 MB/s. The SanDisk Ultra uses UHS-I.

While the card supports Full HD video, its UHS Speed Class 1 (U1) rating may not consistently provide the sustained write speeds required for high-bitrate 4K video recording. For reliable 4K recording, a card with a higher speed class, such as UHS Speed Class 3 (U3) or a higher-tier card, is recommended.

The card is waterproof and designed to protect data even if submerged. However, it's best to retrieve it quickly, dry it thoroughly with a soft cloth, and let it air dry completely before attempting to use it. Ensure the contacts are clean and dry.

SanDisk typically offers a limited lifetime warranty on its Ultra series SD cards. However, warranty terms can vary by region and retailer. Please refer to the official SanDisk website or your purchase documentation for precise details.

The number of photos depends on the image resolution and file format. For example, at a typical resolution of 12 megapixels in JPEG format, you could store tens of thousands of photos. For RAW files, the capacity would be significantly less.

Ensure the card is fully inserted. Try cleaning the card's contacts with a dry, lint-free cloth. Restart your device. Test the card in another compatible device or a card reader to rule out a device-specific issue.

The file system may be corrupted. Try formatting the card using your camera or a computer (ensure important data is backed up first). Ensure the device's firmware is up to date.

Ensure you are using a compatible USB 3.0 or higher card reader connected to a USB 3.0 or higher port on your computer. Verify that the transfer software or operating system is not throttling the speed. Clean the card contacts.

This could indicate a faulty card. Back up any recoverable data immediately and consider replacing the card. Avoid writing data to the card until it's replaced.
