The SanDisk Extreme PRO 256GB microSDXC brings the PRO line’s 200MB/s QuickFlow reads to the 256GB capacity — V30/U3-guaranteed 4K recording, A2 app performance, four-proof durability, and the full-size SD adapter in the box. The card for shooters who offload on deadline.
Speed
200MB/s — PRO-grade offloads
QuickFlow pushes reads to 200MB/s with a compatible reader; writes up to 140MB/s keep bursts and high-bitrate video fluid, with V30 as the guaranteed sustained floor that stops recordings dropping frames.
Capacity
256GB — roughly 8 hours of 4K
About 8 hours of 4K 30fps footage per card — sized for shooters who balance capacity against the discipline of regular offloads.
Reliability
Four-proof, recovery included
Temperature, water, shock and X-ray proof, with the RescuePRO Deluxe recovery licence in the box — one recovered shoot pays for the card.
Right choice if you…
✔ Shoot 4K professionally and offload on deadline
✔ Want SanDisk’s fastest UHS-I line at this size
✔ Need the SD adapter for drone-to-DSLR workflows
✔ Value the guaranteed V30 floor over peak-figure marketing
Consider something else if…
✖ Deadlines are relaxed — the standard Extreme line records identically for less
✖ You need more room — see the SanDisk Extreme PRO 512GB
✖ A smaller card suits your workflow — see the SanDisk Extreme PRO 128GB

Frequently Asked Questions
PRO vs standard Extreme — worth it?
In-camera both guarantee V30, so recordings are identical. The PRO earns its price on offload speed (200MB/s with a QuickFlow reader) and heavy burst work.
Do I get 200MB/s in any reader?
Peak needs a QuickFlow-compatible reader such as SanDisk’s own; standard UHS-I hardware reaches ~104MB/s. In-camera performance is unaffected.
How much 4K fits on 256GB?
Roughly 8 hours of 4K 30fps footage.
Steam Deck / Switch suitable?
Yes — the A2 rating delivers the fast random reads game loading wants.
