What is the difference between the microSD cards that Campbell Scientific sells and the cards that are commonly used in the consumer electronics at home?
Campbell Scientific sells, and embeds in their products, microSD cards that have single-level cell (SLC) memory. In contrast, many electronics retailers sell microSD cards that have multi-level cell (MLC) memory. The difference between these two types of memory is significant.
- The SLC microSD cards from Campbell Scientific are better suited for industrial and environmental applications where wide operating temperatures, low power consumption, and longevity are very important. Most SLC memory cards are designed with industrial applications in mind and, therefore, often have additional perks such as enhanced protection from ESD (electrostatic discharge) and mechanical damage.
- The MLC microSD cards commonly available at electronics retailers are less expensive, but they are generally not well suited for the majority of applications in which Campbell Scientific data acquisition products are used.
