The 256GB 300S UHS-I SDXC Memory Card from Transcend can capture 4K, 3D, and Full HD video, plus raw and JPEG still images and photo bursts. It has a capacity of 256GB and features a speed class rating of V30, which guarantees minimum write speeds of 30 MB/s. If your device does not support the V30 standard, this card also supports the U3 standard, which likewise guarantees minimum write speeds of 30 MB/s. Read speeds are supported up to 100 MB/s and write speeds max out at 40 MB/s. A built-in write-protect switch helps to safeguard against the accidental erasure of card data.

While this card has been designed for cameras that are UHS-I / V30 / U3 compatible, it may be used in devices that do not support UHS-I / V30 / U3. However, bear in mind that this card will then default to your device's speed class and bus rating, such as UHS-I and U1, which supports minimum write speeds of 10 MB/s, or Class 10, which also supports minimum write speeds of 10 MB/s.

As with most Transcend cards, this memory card is shockproof, X-ray proof, and waterproof, while also being able to withstand static, plus temperatures from -13 to 185°F, allowing you to take this card with you into extreme environments, such as snow and deserts. Should the card's data become compromised, you also benefit from Transcend's free RecoveRx software to help recover deleted content, including photos, documents, music, and videos.
