  • 1TB capacity stores extensive 4K footage and apps
  • Read speeds up to 245MB/s accelerate file transfers and editing workflows

Capacity & Target User

The SanDisk Extreme 1TB microSDXC card delivers UHS-I U3 and V30 rated performance for creators who need large, fast removable storage. It suits drone pilots, action-camera users and handheld-gaming enthusiasts recording 4K UHD or 5K point-of-view footage. The A2 rating also helps Android devices load apps more quickly.

Host Compatibility Check

Verify that your device accepts microSDXC cards and supports the UHS-I bus to reach the quoted speeds. A U3 or V30 capable host is required for sustained 4K video recording; older readers may fall back to lower speeds. Confirm the card’s physical size fits your slot and that your operating system can address 1TB of exFAT formatted space.

App & Adapter Benefits

The bundled SanDisk Memory Zone app provides a single interface to view, move and back up files across internal storage, the card and cloud services. A microSD-to-SD adapter is included so the card works in full-size SD slots on laptops, card readers or cameras without a separate purchase.

Questions about this item

Does the 1TB card come with an SD adapter or reader, or must I buy one separately?

The 1TB microSDXC card is sold on its own. An SD adapter or USB card reader is not included and must be purchased separately if your device lacks a microSD slot.

Which capacity should I choose if I need the highest write speed for 4K video?

The 256GB, 512GB, and 1TB models all share the same maximum write speed of 170MB/s. The 128GB version is not rated for that speed.

What does the 245MB/s read speed mean when I copy files to my laptop?

The 245MB/s figure is the peak sequential read rate under ideal conditions. Real-world transfer rates will be lower and depend on your card reader, USB port, and file sizes.
