256GB is the capacity that removes storage anxiety from any serious shoot. The SanDisk Extreme 256GB microSDXC holds approximately 8 hours of 4K 30fps GoPro footage, or a full multi-day photography trip in RAW format, without needing to swap cards. At 190MB/s read and 130MB/s write - the higher write speed stepping up from the 128GB model - it sustains 4K and 5K UHD recording without dropped frames and clears the card quickly at the end of the day. SanDisk QuickFlow Technology pushes read speed beyond the standard UHS-I ceiling, making large offloads faster when paired with a compatible reader. V30 and U3 guarantee the minimum 30MB/s sustained write for 4K capture. A2 ensures smooth app performance for Android and Nintendo Switch users. Four-proof durability means the card survives the conditions that come with outdoor use. RescuePRO Deluxe is included for accidental file recovery. Lifetime SanDisk warranty.

190/130 MB/s

Faster Write Than 128GB Model

At 256GB and above, the SanDisk Extreme delivers 130MB/s write - a significant step up from the 90MB/s of the 128GB model. This matters for high-bitrate video recording and rapid RAW burst shooting: 130MB/s write handles demanding workflows where 90MB/s would produce occasional buffer stalls. 190MB/s sequential read with QuickFlow Technology means a full 256GB of 4K footage transfers to a laptop in around 22 minutes rather than over 40. For photographers using mirrorless cameras capable of sustained 20fps RAW bursts, the higher write speed of the 256GB card is a practical advantage over smaller capacities.

256GB Capacity

All-Day Shooting Without Card Swaps

256GB eliminates the mid-shoot card management that smaller capacities require. A GoPro Hero recording 4K at 30fps fills the card in roughly 8 hours of total footage. A DJI Mavic drone recording 4K at 60fps has enough space for a full day of aerial work. A mirrorless camera shooting 24MP RAW files stores approximately 5,000 images before the card fills. For multi-day trips, hiking expeditions, events, or any situation where stopping to clear or swap cards is not practical, 256GB provides genuine shooting confidence. The card also holds substantial app libraries for Nintendo Switch users - storing dozens of full game titles simultaneously.

4-Proof + RescuePRO

Field-Ready · Recovery Included

Shock, temperature, waterproof and X-ray resistant construction covers the conditions that cards encounter in outdoor and travel use - drops, rain, temperature swings from cold mountain air to hot beach sun, and airport security X-ray scanning. For the data on the card, RescuePRO Deluxe recovery software (included as a download code) can restore accidentally deleted photos and videos. Given that 256GB can hold an entire trip's worth of irreplaceable images, having recovery software available on the same card it's registered to is a practical assurance. A2 performance ensures smooth operation when the card is used for app and game storage on Android devices or Nintendo Switch.

Great choice if you…

✔ Shoot 4K or 5K video on a GoPro, DJI drone or action camera
✔ Want all-day shooting capacity without swapping cards
✔ Shoot high-resolution RAW bursts on a mirrorless camera
✔ Travel and want large capacity plus field-ready durability
✔ Need 130MB/s write speed for demanding recording workflows
