MicroSDXC memory card PNY microSD Express 256 GB UHS‑I Read 890 MB/s Write 750 MB/s U3 V30

PNY microSD Express 256 GB microSDXC delivers PCIe Gen3x1 performance for faster load times and large-capacity storage for gaming and high-resolution video capture. With read speeds up to 890 MB/s and write speeds up to 750 MB/s, this UHS‑I microSD card is designed to accelerate game launches, enable rapid downloads and support sustained recording for high-bitrate 4K/8K video. The card features an A1 application performance rating and a durable construction that resists shock, drops, water, temperature extremes and X-rays.

Advantages

High sequential read and write throughput reduces game and app load times and shortens file transfer windows. PCIe Gen3x1 microSD Express technology provides superspeed performance while maintaining backward compatibility with existing microSD and UHS‑I devices. Built-in thermal monitoring and heat dissipation design improve sustained performance under heavy workloads. A1 app performance enables running and launching applications directly from the card.

Suitable for

• Next‑generation gaming consoles that support microSD Express (for example Nintendo Switch® 2)
• High-bitrate 4K/8K video recording and fast action cameras or drones
• Expanding mobile device storage for apps, large game libraries and media

When it may not be suitable

If your device does not support microSD Express PCIe Gen3x1 hosts, you will be limited to legacy UHS‑I speeds and won’t reach the card’s maximum throughput. For simple, low-capacity needs such as occasional photo storage or basic phone backups, this high-performance card may exceed requirements and budget.

How to use

Insert the microSD card into a compatible host device’s microSD slot or use an appropriate adapter or reader for transfer to a computer. For maximum performance on supported devices, ensure the host supports microSD Express (PCIe Gen3x1) and that firmware is up to date. Format the card in the host device before first use if prompted and use the card for installing games, storing high-resolution video, or running apps directly when the device supports A1 application performance.

What to consider before purchase

• Verify that your device supports microSD Express (PCIe Gen3x1) to achieve maximum speeds
• For backward compatibility, check that the device accepts microSDXC and UHS‑I / UHS‑II cards
• Match performance class (U3, V30, A1) to your recording and app needs
• Consider capacity requirements — 256 GB may be necessary for large game libraries or extensive 4K/8K footage

Recommendations

Use this PNY microSD Express card in devices that explicitly support microSD Express for best results; keep device firmware updated and avoid extreme temperature exposure during sustained high-speed transfers to maintain performance and longevity.
