Based on the company's 3D vertical NAND (V-NAND) flash memory technology, Samsung has introduced the 850 PRO SSD (Solid State Drive). Suitable for use in high-end PCs and workstations, the SSDs deliver sequential read performance up to 550MBps, write performance of up to 520MBps, random read performance up to 100,000IOPS and random write speeds up to 90,000IOPS.

Samsung has claimed that the 850 PRO SSD offers the highest level of performance among SSDs using the SATA III (6Gbps) interface. A Dynamic Thermal Guard feature, maintaining ambient temperature, prevents potential data loss due to overheating.

Featuring a proprietary vertical cell structure, Samsung's V-NAND technology overcomes the density limit currently facing planar NAND architecture used in conventional flash memory. This significantly improves speed, endurance and energy efficiency.

"With the new 850 PRO V-NAND SSD, Samsung is introducing the next major evolution of SSD technology, taking the lead in delivering high-density SSDs with outstanding endurance, performance and energy efficiency. We are fully committed to establishing an innovative computing environment by providing customers with leading-edge V-NAND SSDs with unrivalled performance," comments Unsoo Kim, Senior Vice President, Branded Product Marketing, Samsung.

The Samsung 850 PRO will be available in 128GB, 256GB, 512GB and 1TB capacities.
