Solidigm

Solidigm is an American company that designs and develops solid-state storage for the enterprise market, with a particular focus on data centres running AI workloads and edge computing deployments. Founded in 2021 and headquartered in Rancho Cordova, California, it operates as an independent US-based subsidiary of SK hynix, the South Korean memory maker, and employs roughly 2,000 people worldwide. The firm resulted from SK hynix's $9bn purchase of Intel's NAND and SSD business, one of the largest technology transactions of the past decade.

Its engineering work spans SSD design, NAND flash technology - including QLC, MLC and NOR Flash - and the NVMe, PCIe and PCI interfaces over which such devices communicate. The company's technical lineage runs back to Intel's memory and interconnect programmes: the first NOR Flash in 1988, co-development of the first MLC NAND, the first data-centre QLC SSD in 2018, and a leading role in defining the PCI, PCIe and NVMe specifications.

Recent products include the D5-P5336, a 122TB PCIe SSD described as the highest-capacity PCIe SSD available, and, in 2025, the world's first liquid-cooled SSD, a development aimed at thermal constraints in densely packed AI infrastructure. Liquid cooling technology, along with high-capacity QLC storage, forms part of the company's stated work on data-centre efficiency and edge deployment.

Solidigm concentrates exclusively on enterprise storage, and describes its workforce as innovators, engineers and problem solvers. Its stated mission is to expand the possibilities of data that fuel human advancement.
