Flashgeheugen Transcend 128 GB MicroSDXC SD300S met adapter

The Transcend 128GB MicroSDXC SD300S with Adapter provides 128 GB of removable storage for mobile devices and cameras. Compliant with A1 Application Performance Class, UHS Speed Class 3 (U3) and Video Speed Class V30 for supported capacities, the card supports fast random and sequential read/write operations with up to 95 MB/s read and 40 MB/s write speeds. The card is designed to resist water, temperature extremes, static, X-rays and physical shock, and includes an adapter for compatibility with standard SD card slots.

Advantages

This microSDXC card offers high random read/write performance required for running and launching mobile apps, meeting A1 specifications (minimum 1,500 IOPS read and 500 IOPS write). For the supported capacity range it also meets U3 and V30 standards for 4K Ultra HD video recording. With read speeds up to 95 MB/s and sustained write performance around 40 MB/s, the card delivers a balance of speed and capacity. Durability features—waterproof (IPX7), temperature proof (-25 °C to 85 °C), static and X-ray resistance, and shock tolerance—help protect stored data in challenging conditions. Transcend’s RecoveRx software is available for recovering accidentally deleted files.

Suitable for

• Expanding storage on smartphones and tablets and running apps from the card
• Recording high-resolution and 4K video on compatible devices (capacity-dependent)

How to use

Insert the microSDXC card into a compatible device’s microSD card slot or use the supplied SD adapter for devices with a full-size SD slot. When using the card to run apps, follow the device’s settings to move or install apps to external storage if supported. For video recording, select the appropriate quality settings on your camera or recorder that match the card’s U3/V30 capabilities. Use Transcend’s RecoveRx software on a computer if you need to attempt recovery of deleted files.

Recommendations

Format the card in the host device before first use to ensure optimal compatibility. For sustained high-bitrate 4K recording choose devices and card capacities that explicitly support U3/V30. Keep backups of important files; durable design reduces risk but does not replace regular backups.
