It is not fair to compair SSD drive makers with HDD drive makers.
Quantum, Alps, IBM, Hitachi, Toshiba, Samsung, Seagate, Western Digital, Conner, these companies all developed their own heads and platters. They all had their own factories, marketing and sales forces, and customer support personnel.
Most of the SSD drive makers don't have any R&D - not directly related to SSD and some of those that do are mostly concerned only with controller IC chips, the boards, casing, connectors, and not the SLC/MLC/TLC NAND flash memory and DRAM chips for caching.
Seagate doesn't need to invest billions and tens of billions of dollars into NAND and DRAM as they can always buy chips from Samsung, Hynix, Intel, Micron, Toshiba, etc., but I know no company buying HDD platters from Seagate and label and distribute them under their own brand names.
SD and CF are another matter. Those portable flash memory chips are also mostly NAND, but the standards of those technologies are largely Japanese. It's Sony, Matsushita of Panasonic, Pioneer, Toshiba, Olympus, Sanyo, Canon, Nikon, and some other Japanese electronics companies that control the development, specification, and licensing of those. It would have become a vastly different market if it were dominated by Taiwanese, or European, or South Korean companies.
The commercial airplane market, especially the market for planes like Boeing 787 and Airbus A380, is much larger. Some airlines order literally by the tens of billions of dollars though it's often divided into several phases. That doesn't make automobile distributors with US$50 million fund in South Africa and Qatar design and sell something faster and larger than A380.
Around half of the companies that first designed and sold controllers for SSD and complete SSD units were South Korean, but only Samsung itself had more than 1 billion dollars. Zalman makes their own SSD's, but its annual revenue is only about US$30,000,000. They don't really make profits. Since they often lose money by selling coolers, cases, power supply units, drives, etc. and SSD is just a very tiny part of their business, just how much money could they have afforded to invest in SSD development?
Compare that at what prices IBM sold their HDD business unit to Hitachi and Conner, Quantum, and Samsung to Seagate.
OCZ doet not decide the price of SSD, either. They have some power, but not as much power as Apple and HP. A Benz or Nissan engine in a Hyundai car may play an important role, but the cost of an engine in most cars is usually negligible. It's still expensive, sometimes thousands in USD, but the differences among the prices of various engine are small enough to say it's negligible as they can only be tiny parts of those among the prices of cars. With MP3 players, even luxurious and proud ones like the iPod players, and SSD drives, it's a different story. Most of the hardware cost go to the NAND makers like Samsung and Intel. That was the real reason why iPod was so successful: Samsung provided NAND at extremely attractive terms to Apple as Samsung guys then lacked self-confidence which Apple had in abundance though it should have been the opposite.
So if you are interested in the deeper side of the SSD industry, sometimes it's better to read EE Times Asia instead of Western websites for gamers and overclocking. Western media are usually too proud to read the deeper sources of news and announcements of East Asia where things are actually made and first tested and leaked.
