en.Wedoany.com Reported - SanDisk is advancing the commercialization of next-generation SDUC standard memory cards, planning to launch two high-capacity products with 4TB and 8TB capacities. According to Notebookcheck, at the Computex exhibition, the SD Association booth showcased information on SanDisk's first SDUC memory cards, not as physical products but in the form of promotional posters.

SDUC stands for Secure Digital Ultra Capacity. This standard was established as early as 2018, theoretically supporting storage capacities up to 128TB, but no products have been released for a long time. SanDisk now plans to introduce 4TB and 8TB models in the Ultra series, with the 4TB version in microSD format and the 8TB version in standard SD format. These memory cards will comply with the SDUC standard, supporting UHS-I (U1) speed class, Video Speed Class 10 (V10), and App Performance Class A1. Additionally, for higher performance needs, the SanDisk Extreme Pro series will launch a 4TB SD-format SDUC card, adopting the UHS-II (UHS Speed Class 3) standard to meet V30 and App Performance Class A2 requirements. This series did not showcase 8TB or microSD options.

Notebookcheck confirmed from multiple exhibiting companies that these SDUC memory cards are about to hit the market, but specific details and pricing information have not yet been announced. It is worth noting that SDUC memory cards require new standard card readers to function, and existing readers, including "new SD Express readers," are not compatible. However, new card readers supporting SDUC, SD Express, and UHS-II are expected to be launched within the year, with initial models already on display at Computex.
