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

Western Digital and Micron have announced 1 TB microSDXC cards designed to accommodate high volumes of high-resolution media. Both cards are currently in the pre-release phase.

Why it matters

The introduction of 1 TB capacity in the microSD form factor expands the storage ceiling for mobile devices and cameras, enabling longer 4K video capture without needing to offload data.

The SanDisk Extreme card features a 160 MB/s transfer speed and a $450 retail price, while the 512 GB version is priced at $200. Micron's c200 card utilizes 96-layer 3D quad-level cell NAND technology to achieve read speeds of 100 MB/s and write speeds of 95 MB/s.

The players

Western Digital

A major global provider of data storage technologies, including the SanDisk brand of consumer flash memory products.

Micron

A developer of advanced semiconductor memory and storage solutions, specializing in high-density 3D NAND flash architecture.

The details

Micron’s card utilizes 96-layer 3D QLC (quad-level cell) NAND, a type of flash memory that stores four bits of data per cell to increase density within the tiny footprint of a microSD card. Western Digital has opted for a high-speed interface to achieve its 160 MB/s rating, though internal controller details for the SanDisk unit have not been released. Both products use the microSDXC (extended capacity) standard to provide 1 TB of storage.

• SanDisk 1 TB cards arrive in U.S. retail shops in April 2027.
• Micron c200 cards become available in select markets in Q2 2027.

The Tech Race

The push toward 1 TB microSD cards follows the industry trend of maximizing flash density using 96-layer 3D NAND and related architectures. This move marks a departure from traditional 512 GB limits, directly competing to capture the market for mobile professional video production.

Consumers looking to store high-bitrate 4K footage on smartphones or handheld consoles can expect these 1 TB cards to reach retail shelves starting in April 2027. Prices for the high-capacity SanDisk model are set at $450, representing a significant price premium over the $200 512 GB option.

The takeaway

The move to 1 TB microSD cards signals that mobile media devices are closing the gap with professional-grade local storage capacities. Watch for retail availability in April 2027 to see if market pricing stabilizes for these high-density consumer drives.
