The Korean electronics giant made great strides last year to bring 1 terabyte (1TB) capacity SSDs to the market with 840 EVO. At this year's SSD Global Summit in Seoul, Samsung introduced the 850 PRO — its new 2.5-inch SATA III flash storage specifically designed for high-end PCs and workstations
The 850 PRO features the company's 3D V-NAND (vertical NAND) technology which vertically integrates cell structure to provide incredible speed, energy efficiency and endurance. Built-in Dynamic Thermal Guard helps keep the drives at an optimal temperature while preventing overheating, and data loss. Thanks to 3D V-NAND, Samsung was able to make super fast, super dense SSDs with a smaller footprint.
How fast are the 850 PRO SSDs? Samsung claims its new SSDs offer the fastest performance using the SATA III (6Gb/s) interface with read speeds up to 550MB/s and write speeds up to 520MB/s. That's up to two times faster than regular 20nm planar NAND flash. Random read performance is also up to 100,000 IOPS (input/output operations-per-second) with random write speeds up to 90,000 IOPS.
