Our take on the SanDisk Extreme 512GB microSDXC

The SanDisk Extreme 512GB microSDXC is a UHS-I card rated U3 and V30, aimed at action cameras, drones and phones that record 4K video. It is one of the fastest UHS-I cards SanDisk sells, with read speeds up to 190MB/s and write speeds up to 130MB/s, and it carries an A2 rating for app performance on Android devices. It is a solid pick for GoPro-style cameras and handheld consoles, though UHS-II cards and newer UFS devices beat it on sustained writes. Owners generally rate it for reliability in cameras and drones.

Questions and answers

Is this card fast enough for 4K video?
Yes. The U3 and V30 ratings cover 4K recording in action cameras, drones and phones. It is not aimed at 8K or high-bitrate cinema cameras.
Does it work in a Nintendo Switch?
Yes. The A2 rating and fast reads suit game loading, and 512GB holds a large game library. Format it in the console before use.
How does it compare with the SanDisk Extreme Pro?
The Extreme Pro line pushes higher write speeds and is better for sustained bursts. This Extreme card is cheaper per gigabyte and fine for most 4K shooting.
Is it compatible with phones and tablets?
It works in microSDXC slots, which most Android phones and tablets have. iPhones need a card reader or adapter.
What is in the box?
The card itself, usually with an SD adapter so it fits full-size slots. No reader or case is included.
How do I avoid a counterfeit card?
Buy from a reputable seller and test the card with a tool like H2testw on arrival. Fakes often show far less real capacity than advertised.
