Samsung unveils SSDs using second generation V-NAND parts

Samsung Electronics has begun mass production of its 3D V-NAND flash devices. The second generation products use 32 vertically stacked cell layers, rather than the 24 found in first generation devices.

The company has launched a range of solid state drives (SSDs) based on the second generation parts, including devices with 128Gbyte, 256Gbyte, 512Gbyte and 1Tbyte options. The SSDs have approximately twice the endurance for writing data, whilst consuming 20% less power than devices featuring planar multilevel cell flash chips. Later this year, Samsung will introduce additional 3D based SSDs, with higher reliability and higher densities.
