SanDisk Extreme PRO 512GB SDXC UHS-I Card (SDSDXXD-512G-GN4IN) – 200MB/s, U3, V30

High-capacity SD storage for full-day shoots with fast buffer clearing.

The SanDisk Extreme PRO 512GB SDXC card gives hybrid photo and video shooters fast, high-capacity storage. Writes up to 140MB/s clear burst buffers quickly, U3 and V30 ratings support 4K recording, and reads up to 200MB/s speed up offloads with a compatible reader.

Why Write Speed Matters for Burst Shooting and 4K

Burst photography fills a camera’s internal buffer in seconds. The camera then writes those images to the card, and if the card is slow, you wait before you can shoot again. In 4K video, a card that cannot sustain the camera’s bitrate stops recording.

The SanDisk Extreme PRO 512GB writes at up to 140MB/s and carries U3 and V30 ratings, so it sustains at least 30MB/s for 4K recording and clears burst buffers quickly. Reads of up to 200MB/s speed up offloading with a compatible reader.

512GB covers a full day of mixed RAW stills and 4K clips for most mirrorless shooters, making it a dependable primary card for travel and client work.

Quicker Offloads in the Edit Bay

Reaching the top read speed requires a reader that supports SanDisk’s extended UHS-I mode. Standard UHS-I readers run at up to about 104MB/s, still far quicker than older cards.

Balanced Capacity for Hybrid Shooters

Hybrid creators switching between stills and video need space for both. 512GB holds thousands of RAW images plus hours of 4K footage.

It is also well suited to cameras with dual SD slots set to record backup copies.

How to Set Up the SanDisk Extreme PRO 512GB SD Card

1. Insert the card into your camera’s SD slot with the label facing the direction shown in the camera manual.
2. Format the card in-camera to create the correct file system and folder structure.
3. Set your image quality or video mode; for 4K, confirm your camera accepts V30 cards for the selected bitrate.
4. After shooting, offload files with a UHS-I reader and eject the card safely before removing it.
