Is now a good time to pay a premium for high-capacity 1 TB smartphone storage?

Western Digital and Micron have both introduced new 1 TB microSDXC cards designed to handle high volumes of photography and 4K video. The releases follow a competitive push to provide higher storage density for mobile electronics.

Why it matters

Expanding storage capacities allow mobile users to record high-resolution 4K video and manage massive photo libraries without needing to offload data constantly. These high-capacity cards address the growing demand for local storage in a mobile-first digital environment.

The SanDisk 1 TB card features transfer speeds of 160 MB/s, while the Micron c200 model utilizes 96-layer 3D quad-level cell NAND technology with read and write speeds of 100 MB/s and 95 MB/s, respectively.

The players

Western Digital

This is a global leader in data storage technology that produces hard drives and flash memory products.

Micron

This is a major semiconductor company specializing in memory and storage technologies including DRAM and NAND flash.

The details

Western Digital unveiled its cards at Mobile World Congress, pricing the 1 TB version at $450 and a 512 GB alternative at $200. Micron’s entry aims to compete in the high-density market by leveraging its proprietary 96-layer 3D NAND architecture.

Timeline

  1. The SanDisk 1 TB cards will arrive in U.S. retail shops in April 2027.

  2. Micron plans for its c200 card to be available in select markets during Q2 2027.

Roadmap

The rollout of 1 TB cards signals a broader industry transition toward high-density flash storage for mobile devices. By moving to 96-layer 3D NAND technology, manufacturers are effectively replacing lower-capacity legacy cards to stay competitive in the high-resolution media era.

Consumers planning to purchase the 1 TB SanDisk card should prepare for a $450 retail price point at launch. These cards offer an immediate upgrade for users who struggle with storage limits on smartphones while recording 4K video or capturing high-resolution photos.

The takeaway

Increased storage density allows mobile users to treat their handheld devices more like desktop workstations for media production. Users should compare the read and write speeds of these cards against their specific device needs to ensure optimal performance for 4K recording.
