Transcend USD430T Series microSD, 256GB Capacity, MicroSDXC Format - TS256GUSD430T

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.

Features and Benefits:

• 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

Applications

• 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

What file-system and specification compatibility can I expect?

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.

How does the A2 performance class affect random operations?

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.

What thermal range is supported for continuous operation?

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.

Which NAND type is used and what does that mean for endurance?

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.
