The market for dual micro SD adapters is primarily driven by two distinct segments: legacy gaming expansion (PSP/PS Vita) and high-speed mobile data transfer (USB-C/3.0). While proprietary memory formats have largely been phased out, the demand for cost-effective conversion tools remains strong among enthusiasts and modern multi-device users.
