Fusion-io is a computer hardware and software systems company based in Cottonwood Heights, Utah, that designs and manufactures what it calls a new memory tier based on NAND Flash memory technology. It was named the number one promising information technology company by The Wall Street Journal in March 2010.

Founded in 2006 and producing products by 2007, it attracted attention in February 2009 by hiring Apple Inc. co-founder Steve Wozniak as its chief scientist.

Fusion-io has partnerships with Hewlett-Packard, IBM, Dell, and Supermicro, which is due in part to its server-centric architecture called ioMemory. IBM’s project Quicksilver, based on Fusion-io technology, showed that solid-state technology in 2008 could deliver the fastest performance of its time: 1 million IOPS. As of December 2009, IBM has offered the High IOPS SSD PCIe Adapter, based on the ioDrive, as the only PCIe-based solid-state storage solution for use in IBM servers. HP worked with Fusion-io to create the IO Accelerator specifically for HP's BladeSystem C-Series servers in March 2009.

Stephan Gary "Woz" Wozniak (born August 11, 1950) is an American computer engineer and programmer who founded Apple Computer (now Apple Inc.) with Steve Jobs and Ronald Wayne. Wozniak created the Apple I computer and co-created the Apple II computer in the mid-1970s, which contributed significantly to the microcomputer revolution of that era.

Wozniak has been referred to frequently by the nickname "Woz" or "The Woz”; "WoZ" (short for "Wheels of Zeus") is also the name of a company Wozniak founded.

Wozniak met Steve Jobs when fellow Homestead High School student, Bill Fernandez, introduced them to each other. In 1970, they became friends when Jobs worked for the summer at Hewlett-Packard (HP), where Wozniak was working on a mainframe computer. According to Wozniak's autobiography, iWoz, Jobs had the idea to sell a computer as a fully assembled printed circuit board. Wozniak, at first skeptical, was later convinced by Jobs that even if they were not successful they could at least say to their grandkids they had had their own company. Together they sold some of their possessions (such as Wozniak's HP scientific calculator and Jobs' Volkswagen van), raised USD $1,300, and assembled the first prototypes in Jobs' bedroom and later (when there was no space left) in Jobs' garage. Wozniak's apartment in San Jose was filled with monitors, electronic devices, and some computer games Wozniak had developed.
