Firstly, this SD card utilizes the Ultra High-Speed-I (UHS-I) interface, a high-performance interface standard ensuring both speed and stability in data transfer.
At a rated speed of Class 10, this means that when operating in UHS104 (SDR104) mode, its minimum speed can reach 10MB/s, while the maximum data transfer rate can reach 104MB/s.
The NAND type used in this SD card has not been disclosed by the official sources. However, considering its massive capacity of up to 4TB and the expected release date in 2025, Western Digital might introduce this SD card as one of the initial products utilizing the upcoming BiCS 9 NAND.
BiCS 9 NAND, as an advanced storage technology, with its high capacity, performance, and low power consumption, undoubtedly provides robust technical support for this 4TB SD card.
Moreover, SanDisk has introduced several other products, including the 2TB SanDisk Extreme PRO SDXC UHS-I memory card, 2TB SanDisk Extreme PRO microSDXC UHS-I memory card, SanDisk SD Express (128GB/256GB), and SanDisk microSD Express (128GB/256GB). These products also employ high-performance storage technology and interface standards, offering a diverse range of choices for users with different needs.
