512GB microSD Express for Gaming & Camera

This 512GB microSD Express card uses a PCIe NVMe interface to reach up to 880MB/s read and 650MB/s write speeds. It is built for Nintendo Switch 2 and works with cameras and PCs. The card carries U3, C10 and A1 ratings for sustained performance.

Simple Slot Install with Adapter Included

Installation is a direct slot insert; the bundled adapter lets you use it in full-size SD slots. The card is waterproof, temperature-proof, humidity-proof, drop-proof, shock-proof, magnetic-proof, x-ray proof and wear-out proof. SanDisk ThermAdapt manages heat through dynamic adaptive thermal control.

PCIe NVMe Speed Needs Compatible Reader

Full 880MB/s read and 650MB/s write require a PCIe NVMe-capable reader such as the SanDisk PRO-READER SD Express Dual Card. With UHS-I or UHS-II devices the card falls back to UHS-I speeds. Sustained write is rated at 210MB/s. Transfer examples: 2-hour HD movie in under 3.5 seconds; 60 minutes of 4K 30 fps video in under 70 seconds; 1,000 10MP RAW photos in 51.7 seconds.

商品問答

How can I verify the card is sustaining 210MB/s write after setup?

Use a benchmark tool that reports sustained sequential write; the card is rated for 210MB/s sustained write when the host supports the PCIe-NVMe interface.

What accessories are included and which are sold separately?

The package includes the 512GB microSD Express card and a microSD-to-SD adapter; the SanDisk PRO-READER SD Express Dual Card is sold separately.

Why choose the 512GB Express version over a standard UHS-I card?

The Express card delivers up to 880MB/s read and 650MB/s write via PCIe-NVMe, roughly 4.4 times faster than the fastest UHS-I cards, and transfers 60 minutes of 4K UHD video in under 70 seconds with the PRO-READER.
