Samsung has unveiled the P9 Express, its fastest microSD card to date. Built on a PCIe interface and NVMe protocol, the P9 Express promises a major performance boost for gamers, creators, and anyone who moves large files on the go.
Why NVMe and PCIe change the microSD game
Traditional UHS-I microSD cards have been a solid choice for phones and cameras, but they can’t match the throughput modern workflows demand. The P9 Express leverages SD Express technology — meaning PCIe lanes and NVMe commands inside a microSD form factor — to push sequential read speeds up to 800 MB/s, roughly four times faster than typical UHS-I cards.
Imagine loading huge game assets in seconds, editing 4K clips from an action camera without long transfers, or moving bulky datasets between devices in a flash. That’s the practical upside Samsung is selling with the P9 Express.
Designed for high-performance gaming and pro workflows
Samsung says the P9 Express is tuned for next-generation consoles and handhelds, naming the Nintendo Switch 2 as a target platform. It’s also aimed at content creators who need fast sequential reads for 4K video editing and rapid file transfers.
Key specs and features at a glance:
- Interface: SD Express (PCIe + NVMe)
- Sequential read speeds: up to 800 MB/s
- Available capacities: 256 GB and 512 GB
- Thermal management: Dynamic Thermal Guard to maintain steady performance under load
- Ruggedness: water, dust, drop, and temperature resistance
Do note: to reach those headline speeds your device must support SD Express. In older slots the P9 will still work, but it will fall back to lower transfer modes and conventional speeds.
Who should consider the P9 Express?
If you are a gamer carrying large game libraries, a videographer editing 4K footage on the move, or someone who frequently swaps large files between devices, the P9 Express is worth a look. For everyday smartphone photo backups the premium performance may be overkill — but for power users it can be transformative.
Availability and pricing are straightforward: Samsung will release the P9 Express worldwide in November. The 256 GB model is priced at £58.59, while the 512 GB variant costs £99.99.
With its NVMe underpinnings, thermal management, and rugged build, the P9 Express signals Samsung’s push to bring SSD-like performance into the tiny microSD format. Whether that speed becomes essential depends on your device and use case, but it certainly raises expectations for what microSD cards can do.
