The Amazon Basics 512 GB Micro SDXC Memory Card is designed for users needing reliable, high-speed storage expansion for a variety of devices. Its key benefit is offering ample space and fast transfer rates for media and applications. A potential caveat is that the usable storage capacity may appear less than advertised due to formatting and operating system differences. This card features A2, U3, and Class 10 speed ratings, durable construction, and includes a full-size adapter for broader compatibility.

A2 is an application performance class for faster app launching. U3 indicates a minimum sequential write speed of 30 MB/s, suitable for 4K video. Class 10 signifies a minimum sequential write speed of 10 MB/s.
The stated capacity (512 GB) uses a decimal measurement (1 GB = 1 billion bytes). Your device's operating system typically uses a binary measurement (1 GiB = 1,073,741,824 bytes) and also reserves space for formatting and firmware. This results in a lower reported capacity, often around 465 GB or more.
You can use it in any standard SD card slot by inserting it into the included full-size adapter. However, the device must support the microSDXC format and capacity for the card to function correctly.
Yes, the card is designed to be water-resistant, along with being shock-resistant, temperature-resistant, X-Ray resistant, and magnetic-resistant.
Amazon Basics typically offers a limited warranty on their storage products. Please refer to the product packaging or Amazon's website for specific warranty details.
On most smartphones and tablets, you can unmount the card through the storage settings. On computers, use the 'Safely Remove Hardware' or 'Eject' option in your operating system before physically removing the card.
Ensure the card is inserted correctly. Try restarting your device. Check if your device supports microSDXC cards and the 512 GB capacity. Format the card using a compatible device if prompted, but be aware this erases all data.
Verify that your device's card reader supports the card's speed class (U3, A2). Ensure the device is not running other intensive processes. Test the card in a different device or reader known to perform at higher speeds.
Safely eject the card from your device before removing it. Avoid removing the card while data is being written. If errors persist, back up any recoverable data and consider reformatting the card. If issues continue, the card may be faulty.
Try formatting the card on a different computer or device. Ensure you are using a reliable formatting tool. If the card repeatedly fails to format, it may be defective.
Setup: Insert the microSDXC card directly into the microSDXC slot on your compatible device. If using the full-size adapter, insert the microSDXC card into the adapter, then insert the adapter into the standard SD card slot of your device.
Compatibility: Ensure your device supports the microSDXC standard and the 512 GB capacity. Most modern smartphones, tablets, cameras, laptops, and gaming consoles released in the last several years are compatible. Always check your device's specifications or user manual.
Care: Avoid exposing the card to extreme temperatures outside its operating range. Keep the gold contacts clean; if necessary, gently wipe them with a soft, dry cloth. Do not attempt to disassemble the card. Store the card and adapter in a safe place when not in use.
