(Image credit: Avi Shetty/LinkedIn) Solidigm is arguably one of the most mysterious storage companies in the industry today. The company is a wholly owned subsidiary of SK hynix , yet unlike its parent company, which produces charge-trap flash memory, it uses floating-gate 3D NAND memory that it develops and manufactures internally at a dedicated fab in Dalian, China. Solidigm originates from Intel's Non-Volatile Memory Solutions Group (NSG), the company's NAND and SSD business unit, which used to have a unique technology strategy that differed from that of other flash and drive producers. To that end, it is not surprising that Solidigm also has a unique positioning as it only offers data center drives , most of which are based on floating-gate memory and proprietary in-house designed controllers. Furthermore, Solidigm is a fully vertically integrated company. (Image credit: Tom's Hardware) (Image credit: Tom's Hardware) Anton Shilov is a contributing writer at Tom’s Hardware.…
