SanDisk
History
SanDisk, founded in 1988 by Eli Harari, Sanjay Mehrotra, and Jack Yuan, is a prominent American manufacturer of flash memory products, including memory cards and readers, USB flash drives, and solid-state drives (SSDs). The company was initially known as SunDisk and was a pioneer in the development of flash memory technology. SanDisk's early focus was on the development of non-volatile memory, which retains data without requiring a constant power supply.
In 1991, SanDisk introduced the first flash-based SSD, which was a significant milestone in the storage industry. This innovation paved the way for the widespread adoption of SSDs in various applications, including consumer electronics, enterprise storage, and data centers. Over the years, SanDisk continued to innovate and expand its product portfolio, becoming a leading player in the flash memory market.
In 2016, SanDisk was acquired by Western Digital, a leading data storage company, for approximately $19 billion. This acquisition allowed Western Digital to enhance its flash storage capabilities and strengthen its position in the storage market.
