SanDisk Ultra SDXC 256GB UHS Class 10 Memory Card, Up to 150MB/s Read Speed

Product Description:

The SanDisk 256GB Ultra SDXC UHS-I Card (SDSDUNC-256G-GN6IN) is a high-capacity, high-speed full-size SD card built for photographers, videographers, and content creators who need generous storage and fast transfers without paying premium prices. With 256GB of space and read speeds up to 150MB/s — engineered with SanDisk's proprietary technology to push beyond the standard UHS-I 104MB/s ceiling — the Ultra 256GB stores tens of thousands of photos and hours of Full HD video, then moves everything to your computer faster than most cards in its class.

The 150MB/s maximum read speed is where the 256GB and higher capacities in the Ultra line deliver a meaningful step up over smaller-capacity Ultra cards. Transferring a full 256GB card — tens of thousands of photos or dozens of hours of video — at 150MB/s takes minutes rather than the extended waits that slower cards impose. For photographers who shoot multi-day events, multi-week trail camera deployments, or high-volume wedding and portrait sessions, fast transfer speeds directly impact how quickly you can begin editing and delivering.

256GB provides massive storage capacity: approximately 68,980 JPEG photos, 4,760 RAW photos, 3,410 minutes of HD video (over 56 hours), or 680 minutes of 4K video (over 11 hours). This is the kind of capacity that lets you load a card at the start of a trip, a season, or a multi-day event and never think about storage again. Trail camera users can deploy for weeks. Wedding photographers can shoot an entire day without swapping cards. Vacationers can capture an entire two-week trip on a single card.

The UHS-I bus with Class 10 and U1 speed ratings guarantees a minimum sustained write speed of 10MB/s, ensuring smooth, buffer-free Full HD (1080p) video recording without dropped frames or interrupted captures. SanDisk's 4-proof durability testing confirms the card is waterproof, shockproof, temperature-proof (operates from -13°F to 185°F / -25°C to 85°C), and X-ray proof — protecting your irreplaceable photos and videos from the real-world hazards photographers encounter routinely. A built-in write-protect switch provides physical hardware protection against accidental deletion or overwriting. Backed by SanDisk's limited lifetime warranty.
