SanDisk (SNDK) perpetual market

SanDisk is a maker of flash memory storage products, a brand long associated with memory cards, USB drives and solid-state drives used in cameras, phones, computers and data centers. Originally an independent pioneer of flash storage, the SanDisk business was acquired by hard-drive maker Western Digital in 2016, and in 2025 it was spun back out as a separate public company focused on NAND flash memory and storage devices. That separation was designed to let the flash business, which is highly cyclical and capital-intensive, operate and be valued on its own. SanDisk competes in the memory market against rivals such as Samsung, SK Hynix and Micron, and its results swing with the supply-and-demand cycles that drive flash prices up during shortages and down during gluts. Growing storage needs from data centers and artificial intelligence provide a longer-term demand backdrop for the NAND flash products at the core of its business.
