Transcend MicroSDXC microSD, U3, A2

This microSD is a removable flash memory card designed to expand storage capacity for devices that accept microSDXC format. It supports high-capacity data storage and is intended for use in environments where sustained video recording and fast app access are required. The card adheres to current SD standards and delivers performance suited to demanding mobile and embedded applications.

• UHS-I Interface for accelerated data transfer speeds • 256GB capacity for extensive file and media storage • U3 and V30 ratings ensure consistent video write performance • A2 classification for improved app load and random I/O responsiveness • TLC NAND for balanced cost and storage density • Rated to operate up to 85°C for high-temperature conditions

• Suitable for action cameras capturing continuous 4K video • Ideal for Android devices requiring Rapid app performance • Used with industrial recorders operating in elevated temperatures • Can be used for dashcams and surveillance systems needing sustained writes

It conforms to the SD specification 6.0 and the microSDXC format, enabling use with hosts that support SD 6.0 and exFAT-compatible file systems for large-volume storage.

The A2 designation specifies enhanced random read/write performance under small I/O workloads, improving app launch times and database access compared with lower app-class cards.

The card is specified to function reliably between a minimum operating temperature of -25°C and a maximum of 85°C, making it suitable for many temperature-challenging installations.

It employs TLC NAND, which offers a higher storage density per die and a trade-off between cost and write endurance suitable for typical multimedia and app-storage use cases.
