Samsung Launches new microSD Express Card P9 Express for Next-gen Gaming and Professional Workflows

Samsung Electronics today announced the launch of its new microSD Express card lineup, the P9 Express, designed to deliver next-gen gaming experiences and optimised for leading platforms, including the Nintendo Switch™ 2.

Based on the PCIe interface and NVMe protocol, SD Express technology significantly enhances data transfer performance compared to UHS-I cards, making it ideal for environments that demand high-capacity processing and fast data transmission.

The P9 Express is especially valuable for hardcore console gamers who frequently enjoy a diverse range of games and Downloadable Content (DLC), often demanding additional storage capacity beyond the internal storage. To meet different gaming needs, it is available in both 256GB and 512GB options. It also provides an ideal solution for multiple users sharing a single console, where ample capacity is required for several different game installations, helping gamers overcome limited internal storage and enjoy a wide variety of titles without compromise. When used with a dedicated SD Express interface, the P9 Express delivers sequential read speeds up to four times faster than UHS-I), enabling creators and professionals to efficiently move large volumes of data from devices to PCs, laptops, or workstations). This combination of high-speed performance and reliability makes the P9 Express an excellent choice for both immersive gaming experiences and demanding professional workflows, such as editing, rendering and managing large media files.

By leveraging ultra-fast transfer speeds, Host Memory Buffer (HMB) support, and advanced Dynamic Thermal Guard (DTG) technology, originally developed for SSDs, the P9 Express delivers a smooth gaming experience comparable to playing directly from internal storage. DTG technology intelligently monitors and regulates the card’s temperature, preventing overheating and maintaining consistent performance, even during long gaming sessions. HMB enhances performance by efficiently utilising the host system’s memory to accelerate data access, further improving responsiveness during gameplay. With maximum sequential read speeds of up to 800MB/s—up to four times faster than conventional UHS-I cards—this combination ensures stability, allowing gamers to stay fully immersed in gameplay without throttling or interruptions.

To protect valuable data—whether it’s saved game progress for gamers or large media files for creators and professionals—the P9 Express features safeguarding against water immersion, extreme temperatures, X-ray exposure, accidental drops, dust, and pressure. These robust protections ensure data integrity and sustainable performance, giving users peace of mind during extended gaming sessions as well as demanding professional workflows.

The 256GB and 512GB) models will be available for purchase in November. The manufacturer’s suggested retail prices (MSRPs) are £58.59 for the 256GB model and £99.99 for the 512GB model.
