SanDisk, a brand now under the wing of Western Digital, is a US-based company recognized for crafting flash memory products. Sanjay Mehrotra laid the foundation of the company back in 1988, establishing its headquarters in Milpitas, California.

SanDisk has carved a name for itself in consumer electronics, primarily owing to its pioneering work in NAND flash memory storage cards and USB drives. It offers an extensive range of solid-state storage devices, including, but not limited to, pen drives, SSDs, and memory cards.

The brand is known for its innovative stride, exemplified by achievements such as creating the first 1TB SD card and developing high-capacity microSD cards. The company underwent a major change in 2016 when Western Digital, a prominent hard drive manufacturer, acquired it for $19 billion.

Post-acquisition, SanDisk has continued to operate as a subsidiary brand under Western Digital, specifically focusing on flash memory solutions. Post-acquisition, some of the key brands associated with the company include WD Blue SSDs, G-Drive, and SanDisk itself.

The business landscape of the NAND flash memory market, where SanDisk competes, is dominated by major players like Samsung, Micron, and SK Hynix. Before its acquisition by Western Digital, SanDisk registered revenues amounting to $3.93 billion in 2015.
