SanDisk microSD Express NVMe 1TB 880MB/s read 800MB/s write

SKU CH-FDB0-1N9SJ

High-capacity microSD card using NVMe technology delivers 880 MB/s read and 800 MB/s write speeds for 4K and 8K video capture

  • Up to 880 MB/s read speeds accelerate 4K and 8K video workflows
  • 800 MB/s write speeds enable rapid large-file transfers and recording
  • NVMe interface delivers 3.5× faster performance than UHS-I cards
  • ThermAdapt technology manages heat for reliable operation up to 185 °F
  • 1 TB capacity stores extensive high-resolution content and games

Capacity and speed

The SanDisk microSD Express card provides 1 TB of storage with sequential reads up to 880 MB/s and writes up to 800 MB/s. It uses a PCIe Gen 3 NVMe interface to reach speeds roughly 3.5 times faster than UHS-I cards. This makes it suitable for 5.3K video capture today and 8K workflows on future devices.

Build integration

The card fits any device with a microSDXC slot, including Android phones, tablets, action cameras, drones, handheld gaming consoles and laptops. It remains backward compatible with UHS-I hosts, though performance will fall to UHS-I limits. An SD Express card reader is required to achieve the quoted transfer rates when offloading to a computer.

Bundled technology

SanDisk ThermAdapt technology manages heat from sustained high-speed operation through a specialised enclosure and adaptive thermal controller. The package contains only the memory card; the PRO-READER SD Express Dual Card reader is sold separately and is needed for the fastest offloads. No additional software utilities are included.

Questions about this item

What limits sustained write speed on the 1 TB card?

The card is rated for 800 MB/s sequential write and 880 MB/s sequential read; sustained throughput will be limited by the host device's PCIe Gen 3 NVMe implementation and thermal conditions.

How does the card handle heat during all-day recording?

SanDisk ThermAdapt technology uses a specially designed enclosure and adaptive thermal controller to keep heat within reliable operating limits across the -13 °F to 185 °F range.

Which reader is required to reach the advertised NVMe speeds?

The SanDisk PRO-READER SD Express Dual Card reader (sold separately) is needed to enable the PCIe Gen 3 NVMe interface and achieve the quoted transfer rates.
