Samsung is in a unique position in the SSD market. It’s the only company in the consumer SSD business with a fully vertically integrated business model and zero reliance on other companies. The controller, NAND, DRAM, firmware and software are all designed and produced by Samsung, whereas other companies only focus on their core strengths and outsource the rest. Even the semiconductor giant Intel has switched to SandForce in their consumer lineup and only their enterprise drives get the complete in-house treatment, which to be honest makes a lot of sense given that enterprise market is the one bringing the fat profits home.
