Based on the PCIe interface and NVMe protocol, the 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 ideal for dedicated console gamers who regularly enjoy a wide variety of games and downloadable content (DLC), often requiring additional storage beyond what is available internally. It is available in both 256 GB and 512 GB options to meet different gaming needs.
The P9 Express 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-I2), enabling creators and professionals to efficiently move large volumes of data from devices to PCs, laptops, or workstations3).
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 solid state drives (SSDs), the P9 Express delivers a smooth gaming experience.
The DTG technology intelligently monitors and regulates the card’s temperature, preventing overheating and maintaining consistent performance, even during long gaming sessions. The HMB support also 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 800MBps, up to 4x 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 six-proof durability, 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. Details
The 256 GB and 512 GB4 models will be available for purchase at Samsung.com and through authorised retailers in Singapore from 17 November 2025. The manufacturer's suggested retail prices (MSRPs) for the Samsung P9 Express are S$89 for the 256 GB model and S$171 for the 512 GB model.

2 Based on internal testing with the P9 Express microSD card 512 GB measured using a PCIe test board, compared to UHS-I microSD cards tested with PRO Ultimate microSD card 512 GB and Samsung readers. Actual performance may vary depending on the host device, interface, usage conditions, and other factors.
4 1GB = 1,000,000,000 bytes. Actual storage capacity may be lower than the labelled capacity. Part of the storage may be used for system files and other storage control purposes.
5 SDR104: 1.8 V signalling, Frequency up to 208 MHz, up to 104 MBps, maximum current consumption 800 mA (varies by test conditions).
6 1 GB = 1,000,000,000 bytes. Actual usable storage capacity may vary. User capacity measured with SD Formatter 3.1 tool with the FAT file system.
7 V30 : Video Speed Class means sustained video capture rates of 30MB/s(V30) which enable to support real-time video recording to UHS Bus interface products. Transfer speeds may vary by host device.
8 Performance results are based on internal testing conditions. Actual read speeds may vary depending on user environment.
9 Stated temperature is defined as the ambient temperature. Sufficient cooling airflow or effective heat-dissipation are recommended to be operated properly on heavier workloads within device operating temperature.
10 Warranties provided herein do not extend to any use of the product for or with continuous recording instruments or any other write-intensive devices, including without limitation security cameras, surveillance systems, dashboard cameras, black box cameras, Internet protocol/network cameras, continuous recording set top box devices and continuous data logging devices like servers, dedicated devices for benchmarking test, the primary drive for certain devices and any other excessive uses.
