Transcend 8 GB SDHC SD Card, Class 4

Transcend SD Card, 8GB Memory Size, Class 4 Speed Rating - TS8GSDHC4

This SD card is a removable flash memory device intended for data storage and transfer in embedded systems and imaging equipment. It offers moderate capacity suitable for routine file storage and logging tasks, and is designed to operate across a wide temperature range for use in industrial and field environments.

Features and Benefits:

• 8GB capacity for storing logs and media files
  Uses MLC NAND for improved write endurance
  Class 4 speed rating for consistent low-bandwidth transfers
  Operates from -25°C to 85°C for harsh conditions

Applications

• Suitable for data logging in automation controllers
  Ideal for firmware distribution and updates in electronics
  Used with industrial cameras for Basic image capture
  Can be used for portable configuration storage in mechanical systems

What flash technology does it use and why does that matter?

It employs MLC NAND, which typically offers a balance between endurance and cost, making it appropriate for repetitive write cycles in control and monitoring tasks.

How does the speed class affect performance in devices?

The Class 4 rating indicates a minimum sustained write performance suited to low-to-moderate bitrate recording and reliable file transfers rather than high-resolution continuous video.

What environmental conditions can it withstand during operation?

It functions within a temperature span from -25°C up to 85°C, allowing deployment in cold storage areas and elevated-temperature enclosures without Active cooling.
