Meet the card that keeps up with your ambitions. The Transcend 300S 256GB microSDXC delivers a massive 256GB of expandable storage paired with the performance headroom modern devices demand. With read speeds reaching 95 MB/s and write speeds up to 40 MB/s, this card handles Full HD, 3D, and 4K Ultra HD video, raw and JPEG still photos, and rapid burst shooting without breaking a sweat.
Smart Performance for Apps and Video
Rated V30, U3, and UHS-I, the 300S guarantees minimum write speeds of 30 MB/s — critical for smooth 4K capture. It also carries the Application Performance Class 1 (A1) certification, meaning it manages a minimum of 1,500 random read IOPS and 500 random write IOPS. The result: Android apps launch faster, multitask smoother, and handle audio, graphics, saved profiles, and in-app permissions with ease. If your device doesn't support UHS-I or V30, the card automatically adjusts to your device's supported bus and speed class.
Built Tough, Backed by Recovery Tools
The 300S is engineered to survive real-world punishment — it's waterproof, shockproof, X-ray proof, and static-resistant, operating in temperatures from -13°F to 185°F. Transcend also includes free RecoveRx software to help recover accidentally deleted photos, videos, music, and documents. A microSD-to-SD adapter is included for use in full-size SD card slots.
