Extreme 512GB microSDXC UHS-I card

This SanDisk Extreme microSDXC card delivers 512GB of storage with UHS-I interface speeds. It reaches up to 190MB/s read and 130MB/s write, rated U3, V30, Class 10 and A2. The card is built to withstand shock, temperature extremes, water and X-rays, and includes a standard SD adapter for broader device compatibility.

For action cameras, drones and 4K video workflows

Photographers and videographers capturing 4K UHD or Full HD footage will benefit from the sustained V30 write performance. App Performance Class 2 support helps mobile devices and handheld consoles load apps faster. Users who need guaranteed minimum write speeds above 30MB/s for 8K or high-bitrate cinema codecs should consider cards with higher video speed class ratings.

V30 sustained write speed decides suitability

The Video Speed Class 30 (V30) rating guarantees a minimum sequential write of 30MB/s, which is the key figure for uninterrupted 4K recording. If your device or workflow demands a higher guaranteed minimum write speed, this card will not meet that requirement.

Questions about this item

What device do I need to reach the 190MB/s read speed shown on this 512GB Extreme card?

A SanDisk Professional PRO-READER SD and microSD reader is required to achieve the stated 190MB/s read speed; other readers may limit performance.

Will this U3 V30 A2 card work in an older camera that only supports Class 10 UHS-I?

Yes, the card is backward compatible with Class 10 UHS-I devices, though it will operate at the host device's maximum supported speed.

How can I verify the 130MB/s write speed is working after setup?

Use a high-quality USB 3.0 card reader and benchmark tool; avoid cheap readers as they can reduce measured speeds.
