Transcend 128 GB Industrial Grade SDXC SD Card, UHS 1

This SD card is an industrial-grade removable memory device designed for data storage and logging in demanding environments. It uses 3D TLC NAND and conforms to SDXC and UHS-I interfaces, delivering sustained video and application-class performance for embedded and industrial systems. The card operates across a wide temperature range and includes firmware functions to preserve data integrity during normal operation.

• Up to 100MB/s sequential read for fast data retrieval
• Up to 85MB/s sequential write for sustained recording
• A2 application class for improved random I/O performance
• TBW 331TB for endurance over heavy write workloads
• Operates -25°C to 85°C for extreme temperature resilience
• IPX7 water resistance to protect against immersion incidents

• Suitable for industrial control system data logging
• Ideal for Vision systems requiring sustained video capture
• Used with edge computing modules needing A2 responsiveness
• Can be used for mobile measurement instruments in fieldwork
• Appropriate for embedded devices with high write cycles

The card employs LDPC ECC, read-retry and global wear-levelling to detect and correct errors and extend NAND lifespan.

A power-shield function monitors voltage and halts communication then writing to reduce corrupted writes during supply drop.

It is specified for 1.5m free-fall drops, 20G vibration up to 2000Hz, and shock profiles per industrial test conditions.

SMART support exposes metrics such as erase counts, spare blocks, power cycles and abnormal power events for diagnostics.
