R1 microSD memory cards are built with original high-quality SLC chips and are subject to rigorous environmental testing. Used with page mapping firmware, it increases the random read and write speed several tens of megabytes per second faster, making it more effective in processing small random writes. The value-adding function of firmware technology also significantly reduces the write amplification factor (WAF), prolonging product life and durability. Furthermore, customized firmware optimizing tools, such as write protect, protect stored contents, ensuring date security and integrity.
Compatible with the latest SD3.0 interface, the Apacer R1-series microSD memory cards are available in capacities of 1 to 8GB despite their small form factor and demonstrate excellent performance while consuming little power.
