SanDisk co-founder Eli Harari developed the Floating Gate EEPROM which proved the practicality, reliability and endurance of semiconductor-based data storage.

In 1991 SanDisk produced the first flash-based solid-state drive (SSD) in a 2.5-inch hard disk drive form factor for IBM with a 20 MB capacity priced at about $1,000.

In 1992, SanDisk (then SunDisk) introduced FlashDisk, a series of memory cards made for the PCMCIA or PC card form factor, so they could be inserted into the expansion slots of many laptops and handheld PCs of the time. Unlike other similar products at the time, FlashDisks did not require a battery to store their contents. SanDisk discontinued their production in 2002, and the highest capacity model had 8 gigabytes of capacity.

In 1995, just before its initial public offering, SunDisk changed its name to SanDisk, possibly to avoid confusion with Sun Microsystems, a prominent computer manufacturer at the time.

On May 10, 2000, the Toshiba Corporation of Japan and the SanDisk Corporation said that they would jointly form a new semiconductor company to produce advanced flash memory, primarily for digital cameras.

In 2005 SanDisk entered the digital audio player market with the release of its first flash-based MP3 player, the SanDisk Sansa e100. As soon as 2006, they became the second largest maker of digital audio players in the United States behind Apple.
