New “S275” Series Product Lineup
This announcement includes the “UHS-I V30 SDXC Card S275 GOLD EVO Series,” the “UHS-I V30 SDXC Card S275 GOLD Series,” the “UHS-I V30 microSDXC Card S275 GOLD EVO Series,” and the “UHS-I V30 microSDXC Card S275 GOLD Series.” Each series will be available in 64GB, 128GB, and 256GB capacities. The cards are designed to provide stable write performance during shooting and efficient high-speed read performance for data transfer after capture. All four “S275” series products are scheduled for release in early September 2026.
Development Background: The Growing Importance of Data Ingest Speed
With the increasing prevalence of 4K video and high-resolution photography, the volume of data handled by cameras, action cameras, drones, and 360-degree cameras continues to grow. Memory cards are now required to offer not only stable write performance during recording but also fast read speeds to shorten the time needed to transfer footage to PCs for editing and backup.
Building on stable video recording performance compliant with V30/U3, the S275 series prioritizes high-speed read performance, achieving up to 240MB/s to 250MB/s. This new series aims to streamline the creative workflow from shooting to data transfer and editing.
