What it does

Sandisk makes NAND flash memory and the products built from it: data-center and PC solid-state drives, embedded storage for phones and devices, memory cards and USB drives. It became a standalone company in February 2025 when Western Digital separated its flash business.

Why it matters

AI training and inference data centers need large amounts of fast flash storage, and Sandisk says its datacenter segment revenue grew more than fivefold in fiscal 2026; it is also co-developing High Bandwidth Flash, a NAND-based memory tier intended to sit near AI processors.

How it makes money

Data-center operators, PC and phone makers, and consumers pay it for flash memory chips, SSDs, embedded storage and removable storage products.
