Samsung has launched a new SSD called 850 Pro that features the new 3D NAND, or V-Vertical NAND modules. According to many SSD experts the Samsung 850 Pro SSD is said to bring revolutionary changes to SSD industry.
The Samsung 850 Pro is the world’s firs to adopt the TLC also known as triple level cells. Over the past 15 years the structure of the NAND flash memory modules has remained unchanged where the grid of cells are arranged adjacent to each other.
Samsung’s new solid state drive has got the cells arranged in the vertical stack that will allow manufactures to easily increase the storage density.
This will make them a more viable hard disk drives replacements. The proprietary Samsung NAND-V adopts a 3D model in which cells are stacked vertically. This will enable the company to the cut the costs of 1TB SSD.
