Samsung launched a new SSD line-up today and it is based on the Korean giant’s cutting edge 3D vertical NAND (V-NAND).

The Samsung 850 Pro series comes in four capacities, 128GB, 256GB, 512GB and 1TB. The spec is impressive and judging by the numbers, the 850 series is a worthy successor to the 840.

The new drives can deliver sequential read performance of up to 550MB/s and write performance of up to 520MB/s. Random read performance looks even better, random read stands at 100k IOPS, while write performance is 90K IOPS.

As for V-NAND, it is Samsung’s proprietary technology designed to maximise density and overcome limitations posed by planar NAND architectures used today. The company says V-NAND offers better endurance, speed and efficiency than planar NAND.
