SanDisk Extreme Pro 200MB/s 512GB SDXC UHS-I Memory Card

The SanDisk Extreme Pro 200MB/s 512GB is a high-capacity professional SDXC UHS-I card for extended production work. It pairs half a terabyte of storage with the family’s fastest speeds: 200MB/s reads and 140MB/s writes. As a result, it suits documentary videographers, event professionals, and anyone shooting long 4K projects without card swaps.

Compatibility

• Works with SDXC and SDXC UHS-I enabled host devices, including DSLRs, mirrorless cameras, camcorders, and laptops with SD slots. In devices without U3/V30 support, the card defaults to the host’s speed class at reduced performance. However, confirm your device supports SDXC before buying, as SDHC-only devices cannot read it.

What Can You Use the SanDisk Extreme Pro 200MB/s 512GB For?

• Extended 4K video production: The V30 rating sustains 4K UHD recording, and 512GB holds full documentary or multi-camera sessions without interruption.
• Multi-day professional assignments: Safaris, festivals, and week-long events fit on one card, which removes mid-shoot card swaps entirely.
• High-volume burst photography: 140MB/s writes clear the buffer rapidly during continuous RAW shooting of sports, wildlife, or motorsport.
• Working archive on the go: The capacity doubles as grab-and-go storage for an active project library via a laptop SD slot.

When Does 512GB Make Sense Over 256GB?

Both capacities share identical 200MB/s read and 140MB/s write speeds, so the decision is purely storage. For instance, documentary shooters, multi-day event coverage, and 4K workflows with infrequent offloads benefit from the doubled headroom. However, if you offload after every shoot, the 256GB card costs less and still delivers the same top-tier performance.

Frequently Asked Questions

Will the SanDisk Extreme Pro 200MB/s 512GB work with my camera?

Yes, provided your camera supports SDXC cards. Most current DSLR and mirrorless models do. However, older SDHC-only devices max out at 32GB cards, so check your manual first.

Do I get the full 200MB/s speed on any card reader?

No. Speeds above the UHS-I standard of 104MB/s require a QuickFlow-compatible reader, such as the SanDisk Professional PRO-READER (sold separately). Standard readers still deliver strong UHS-I performance.

Is this card fast enough for 4K video?

Yes. The V30 and U3 ratings guarantee a 30MB/s minimum sustained write speed, and the 140MB/s peak writes give generous headroom for high-bitrate 4K recording.
