FAQs
What is the difference between UHS-I and UHS-II?
UHS-I (Ultra High Speed I) is a bus interface standard offering theoretical speeds up to 104 MB/s. UHS-II offers a second row of pins for significantly faster theoretical speeds (up to 312 MB/s) and requires a UHS-II compatible device and card.
What does A2 rating mean for this card?
The A2 rating signifies enhanced application performance, allowing the card to execute commands faster, leading to quicker app loading times and smoother operation when used in compatible smartphones and tablets.
How do I protect my data if the card fails?
Regularly back up important data from the memory card to another storage medium, such as a computer's hard drive, cloud storage, or another reliable drive. This is the best defense against data loss.
Can I use this card in older devices that only support SDHC?
No, this is a MicroSDXC card. Devices that only support SDHC (or SDXC with lower speed classes) may not be compatible or may perform at significantly reduced speeds. Always check your device's specifications for MicroSDXC compatibility.
How much 4K video can 512GB hold?
The card can hold approximately 30 hours of 4K/UHD video. This is an estimate and actual recording time can vary based on the video's bitrate and compression settings.
Is the included SD adapter a standard speed adapter?
The included adapter allows the microSDXC card to be used in standard SD card slots. Its own transfer speed is limited by the adapter's internal circuitry, but it is designed to work seamlessly with the card's performance capabilities for general use.
Troubleshooting
Card not recognized by device
Ensure the card is fully inserted. Try cleaning the card's contacts with a dry, soft cloth. Test the card in another compatible device or with a different card reader. If using the SD adapter, ensure the microSDXC card is correctly seated in the adapter.
Slow transfer speeds
Verify that your device and card reader support UHS-I U3 and V30 speeds. Using a slower card reader or an older device interface will limit performance. Ensure the card is not nearly full, as performance can degrade.
Data corruption or errors
Safely eject the card from all devices before removal. Avoid interrupting read/write operations. Reformat the card in the device you intend to use it with (note: this erases all data). If errors persist, the card may be failing.
Device shows card as full despite having free space
Perform a safe eject and reinsert the card. Try formatting the card on the device (backup data first). Some devices may reserve a small amount of space for system files.
