What is wear levelling?

Wear levelling is a flash memory management technology that helps extend the lifespan of a microSD™ card by distributing data evenly across the memory cells. Without wear levelling, the same areas of memory could be written to repeatedly, causing them to wear out more quickly than others. By balancing where information is stored, wear levelling helps maximise the usable life of the card.

TrailBit™ incorporates wear levelling technology to support dependable long-term performance across compatible devices. Whether you're regularly recording adventures, transferring files or using your microSD™ card every day, wear levelling helps ensure storage is used efficiently throughout the life of the card, contributing to consistent performance over time.
