Industrial MicroSD

Industrial grade MIcro SD card for more resistant and durable Coldcard backups than a conventional SD card.

1. True SLC Design

• SLC (Single-Level Cell) : This memory technology stores a single bit per cell, which means it is faster, more reliable, and more durable than other types of flash memory such as MLC (Multi-Level Cell) or TLC (Triple-Level Cell). The "True SLC" indicates that this is true SLC memory, not an emulated or optimized version of SLC.
• Advantages : A microSD card with a True SLC design will have better endurance (higher write/erase cycles), better speed performance, and better error tolerance, which is crucial for industrial or mission-critical applications.

2. Wear-Leveling & Block Management

• Wear-Leveling : This technology allows write cycles to be evenly distributed across all cells on the card, preventing premature wear of specific areas. This extends the overall life of the card.
• Block Management : This feature efficiently manages data blocks, including bad block management. This ensures that data is stored reliably even if some blocks fail.

Tested under extreme conditions:

• Bending and twisting test : The card has been tested to withstand bending and twisting forces, ensuring it can withstand mechanical handling without damage.
• Salt Spray Test : This test checks the board's resistance to corrosion caused by a salty environment, such as marine environments. This is especially important for outdoor applications or in corrosive environments.
• Solar Radiation : The card has been tested to withstand the effects of solar radiation, which is crucial for outdoor applications where it might be exposed to direct sunlight for extended periods.

4. High temperature variation (-40°C to +85°C)

• The card is designed to operate in an extreme temperature range of -40°C to +85°C. This means it can be used in extreme cold or intense heat without compromising its performance or durability. This feature is particularly useful for industrial, military or harsh environment applications.

In other words, this microSD card is specifically designed for critical applications where reliability and durability are essential....
