Indilinx was a minor name during the early years of SSD development, partly because it did not even exist during the first few years of NAND-based SSD.
Here are some old news links from 2007.
Samsung's third-generation SSD (PATA -> SATA 150 -> SATA 300)
Intel visiting Mtron, Samsung, and ONS of South Korea (Mtron made SSD controller, developed and sold SSD for servers and PC, Samsung made NAND, SSD, desktops and laptops, tablets and smartphones, servers, and ran hundreds of businesses that ran those servers, ONS made some of the world's first 2U rackmount type servers running RAID-1 NAND SSDs made by Mtron)
And even older, Mr. Hwang, the former Samsung executive, in 2005
Indilinx (after bought by OCZ) in 2012
Why did Mtron fail while Indilinx survived? Mtron tried to compete directly against Samsung and Intel, but everyone inside South Korea knew quite well Samsung had been years ahead of Mtron and it was Hwang himself that lead the development and popularization of NAND and SSD - it was also in these years Steve Jobs at Apple met him to discuss NAND and SSD - so it should have been obvious nobody wanted to invest more into Mtron. Why Mtron actually disintegrated was not publicized in detail. Hwang quit his job as the head of semiconductor business at Samsung to save Lee Gunhee in 2008 from the regime and other forces that tried to destroy Samsung in similar ways they destroyed Daewoo and Hyundai. Under his leadership, Samsung experimented SSD in desktops, laptops, servers, and other types of devices for some years and it was soon widely known that Samsung employees were using laptops with Samsung SSD inside, not for sale yet. That was before 2005. Hwang announced his intention in September 2005 - quite an unlikely action for a Korean, but then he was educated at Stanford and worked for Intel. Indilinx was started by three South Koreans living near the headquarter of Samsung in late 2006. The key people of Indilinx were all those that spent around ten years working with flash semiconductor and flash storage.
But how could Indilinx survive when a much bigger and much more complete player, Mtron, failed ending in a disaster for all (except Samsung itself)? Easy, Indilinx needed to feed only far less than 50 people. And since they just developed the controller, they didn't require US$100,000,000. What they needed was more like one hundredth of that. Since Indilinx already had an office in Silicon Valley, it was relatively easy to keep in touch with OCZ and OCZ was Indilinx's largest customer. OCZ bought Indilinx and Indilinx, or its owners, became a large shareholder of OCZ in return.
