Samsung has started sampling its 256GB SD Express microSD cards, with a launch later this year. Mass production of 1TB UHS-1 microSD cards has begun, expected in Q3 2024. The 256GB card offers up to 800 MB/s read and 958 MB/s write speeds, outpacing SATA SSDs. Samsung aims to meet the demands of mobile computing and on-device AI with faster and larger storage solutions (Samsung Unveils microSD Cards).
Samsung has revealed the commencement of the sampling phase for its 256GB SD Express microSD cards. Additionally, the company has initiated the mass production of its 1TB UHS-1 microSD card.
The Express microSD card is slated for launch later this year, while the 1TB UHS-1 cards are expected to be available in the third quarter of 2024 (Samsung Unveils microSD Cards).
Hangu Sohn, Vice President of the Memory Brand Product Biz Team at Samsung Electronics, stated, “With our two new microSD cards, Samsung has effectively addressed the growing demands of mobile computing and on-device AI.”
Samsung has announced that the 256GB SD Express microSD card offers a read speed of up to 800 MB per second and write speeds of up to 958 MB per second.
The read speed reflects the time it takes to access a file stored on the card, while the write speed indicates the time required to save a file on the card (Samsung Unveils microSD Cards).
In comparison, Samsung has stated that its SD Express microSD card is 1.4 times faster than SATA SSDs (Solid State Drives), achieving sequential read speeds of up to 560 MB per second.
The upcoming SD Express cards are anticipated to be four times faster than traditional UHS-1 memory cards, which have read speeds reaching up to 200 MB per second.
To enhance performance and reliability, Samsung has incorporated Dynamic Thermal Guard (DTG) technology into its 256GB SD Express microSD card, ensuring optimal temperature maintenance even during prolonged usage.
With its next-generation microSD card lineup, Samsung aims to provide storage solutions for devices capable of running on-device AI (Samsung Unveils microSD Cards).
As AI functionalities increasingly operate independently of the cloud, the size and speed of storage become critical specifications.
Devices equipped with faster and larger storage capacities will be better suited for executing data-intensive AI tasks, such as running AI image generation models directly on the device.
