Sandisk is the NAND flash and SSD business separated from Western Digital in February 2025, now an independent public company. Its fiscal fourth-quarter 2026 revenue was $8.965 billion, up 51% sequentially, with management attributing roughly two-thirds of the increase to pricing; datacenter revenue was $2.977 billion. Its Stargate QLC enterprise SSDs have begun initial revenue shipments, making it a key test of whether AI-era flash demand outlasts a pricing cycle.
