Samsung Unveils Groundbreaking MicroSD Cards for Future Mobile Computing and AI

Samsung Electronics, a global leader in cutting-edge memory technology, has announced the launch of its innovative 256GB SD Express microSD card, having an unprecedented sequential read speed of up to 800MB/s, alongside the start of mass production for its 1TB UHS-1 microSD card.

These latest additions to Samsung’s microSD card range are designed to meet the increasing demands of modern mobile computing and on-device AI, offering high performance and capacity in the compact form of a microSD card.

Hangu Sohn, Vice President of the Memory Brand Product Biz Team at Samsung Electronics, expressed that these new microSD cards are Samsung’s answer to the evolving needs of mobile computing and on-device AI.

Despite their small size, these cards are designed to deliver SSD-like performance and capacity, enabling users to leverage the full potential of advanced and upcoming applications.

Industry’s First SD Express MicroSD Card Achieves Speeds of 800 MB/s

Samsung sets a new industry standard with its SD Express microSD card, the first of its kind to employ the SD Express interface for unmatched performance.

This achievement comes from a fruitful partnership with a customer to produce a tailored product that stands out in the market.

The SD Express microSD card by Samsung is engineered for efficiency, featuring a low-power design and firmware optimized for top-tier performance and effective thermal management.

While traditional microSD cards are limited to read speeds of 104MB/s, Samsung’s innovative approach has increased this to 800MB/s—surpassing SATA SSDs and significantly outpacing conventional UHS-1 cards.

The incorporation of Dynamic Thermal Guard (DTG) technology ensures that the SD Express microSD card operates at an optimal temperature, maintaining consistent performance and reliability even during extended use.
