High-Capacity Storage for Everyday Use

With 512GB of storage, this microSD card provides room for a large collection of digital files. Use it to expand available storage on compatible devices and keep important media and documents accessible.

Application Storage for Compatible Devices

The Transcend 300S series is designed with mobile application storage in mind. Random read/write performance is important when applications retrieve small pieces of data from different locations.

Important capacity note: The supplied product information states that A1 Application Performance Class compliance applies only to 128GB cards. Therefore, A1 certification should not be assumed for this 512GB model.

Speed and Video Recording

The Transcend 300S series is designed for applications that require efficient data transfer and video storage. The supplied information lists read speeds of up to 95MB/s and write speeds of up to 45MB/s, while U3 and V30 compliance is specified only for 128GB cards.

For the 512GB version, confirm the exact speed ratings and 4K recording compatibility before purchase, as the supplied specifications do not establish that the 512GB model carries the same U3, V30, or A1 ratings.

Transcend microSD cards undergo testing for resistance to various environmental and physical conditions:

  • Waterproof: Meets JIS IPX7 standards, withstanding immersion in 1 metre of water for up to 30 minutes.

  • Temperature Proof: Designed for temperatures from -25°C to 85°C.

  • Static Proof: Meets EMC IEC61000-4-2 standards for resistance to static electricity.

  • X-Ray Proof: Resistant to airport X-ray exposure.
