512 GB microSDXC Extreme card

The SanDisk SDSQXAV-512G-AN6MA is a 512 GB microSDXC memory card from the Extreme line. It targets photographers and videographers who need high-capacity removable storage for cameras, drones or action cams. The card carries UHS-I U3 and V30 speed ratings plus Application Performance Class A2.

Sustained write performance

Maximum read speed reaches 190 MB/s while maximum write speed reaches 130 MB/s. The V30 rating guarantees a minimum sustained write speed of 30 MB/s, which keeps 4K video recording stable during long sessions. A2 rating helps apps loaded on the card launch and run smoothly.

Host device requirements

Your device must support the microSDXC format and UHS-I speeds to reach the quoted transfer rates. Verify that the host accepts cards up to 512 GB capacity. The card is waterproof, temperature proof, X-ray proof and shock proof for rugged use.

Questions about this item

Does the 190 MB/s read speed cause noticeable heat or power draw when the card runs continuously in a 4K camera?

The card is rated for temperature-proof operation and draws only the standard microSD bus power, so extended 4K recording sessions do not produce noticeable heat or extra battery drain.

What host device specification must I already have to reach the 130 MB/s write speed?

Your device needs a UHS-I U3 or V30 compatible microSDXC slot; without that interface the card will fall back to lower speeds.

Will this A2-rated card work reliably in my older action camera that only supports Class 10?

Yes, the card is backward compatible with Class 10 hosts, but write performance will be limited to the camera's maximum supported speed.
