Samsung’s New microSD Cards Bring High Performance and Capacity
Samsung Electronics announced that it has started sampling its 256-gigabyte (GB) SD Express microSD card with sequential read speed of up to 800 megabytes per second (MB/s) and has commenced mass production of its 1-terabyte (TB)3 UHS-1 microSD card.
Thanks to its low-power design as well as firmware technology optimized for high-performance and thermal management, Samsung’s SD Express microSD card offers performance equivalent to SSDs in a small form factor. While read speeds for traditional microSD cards based on the UHS-1 interface were limited to 104MB/s, SD Express was able to boost it to 985MB/s, although commercial availability of the latter were not viable in microSD cards until now.
The sequential read speed of Samsung’s SD Express microSD card reaches up to 800MB/s — 1.4 times faster than SATA SSDs (up to 560 MB/s) and more than four times faster compared to traditional UHS-1 memory cards (up to 200 MB/s), allowing improved computing experiences in various applications, including PCs and mobile devices. To ensure stable performance and reliability for the small form factor, Dynamic Thermal Guard (DTG) technology maintains the optimum temperature for the SD Express microSD card, even during long usage sessions.
The new 1TB microSD card stacks eight layers of the company’s 8th generation 1-terabit (Tb) V-NAND within a microSD form factor, realizing the high-capacity package that used to be possible only in SSDs. The new 1TB microSD card passes the industry’s most rigorous test settings and offers reliable usage even in challenging environments, with features such as water protection, extreme temperature, drop-proof design, wear-out protection, as well as X-ray and magnetic protection.
