Details
SanDisk microSD Express Memory Card is a hybrid, next-generation storage solution that merges a traditional microSD form factor with an advanced PCIe Gen 3x1 NVMe 3.1 interface. This enables SSD-like speeds of up to 880 MB/s read and 650 MB/s write when paired with a compatible Express host device or the SanDisk PRO-READER SD Express Dual Card.
Key Specifications & Features
- Interface: PCIe 3.1 NVMe (backward compatible with standard UHS-I/UHS-II slots at lower speeds)
- Speeds: Up to 880 MB/s read; up to 650 MB/s write (480 MB/s for 128GB variant)
- Capacities: Available in 128GB, 256GB, and 512GB / 1TB variants
- Thermal Control: Features proprietary ThermAdapt technology with an adaptive thermal controller to prevent overheating during high-speed tasks
- Durability: Waterproof, shock-proof, temperature-proof, and X-ray proof
- UHS-II Hardware Limitation: While backward compatible with everything, it is specifically configured to drop down to UHS-I speeds when used in legacy devices. This means if you put it in a high-end camera that supports UHS-II, the card will still run at UHS-I speeds. You must have an explicit SD Express / microSD Express host to see the 880 MB/s speeds
