From PC World: Enthusiasts, start your drooling: On Tuesday, Samsung launched the first solid-state drive packing the company's cutting-edge 3D V-NAND flash memory. Early reviews suggest the technological tweaks in the Samsung 850 Pro SSD line indeed deliver face-melting levels of performance.
The secret sauce is the "V" in "V-NAND," which stands for "vertical." Whereas traditional NAND cells are laid out on a horizontal plane, Samsung's V-NAND stacks 32 layers of flash cells atop each other. The company claims three advantages for the 850 Pro line from V-NAND technology: twice the durability of normal SSDs, for one—Samsung offers a warranty good for ten years or 150TB of writes with these drives. V-NAND also offers a claimed 20-percent boost in power efficiency. Finally, Samsung promises enhanced performance, with claimed sequential read/write speeds up to 550MBps/520MBps.
Samsung sent 850 Pro SSDs to the enthusiast-focused reviewers at AnandTech, Hot Hardware, Tweak Town, and Tom's Hardware, and the early verdict was unanimous: The 850 Pro line's speed, power efficiency, endurance, and even its software features surpass the competition's. Though enthusiast SSDs from competing brands put up a decent showing against Samsung's latest, the 850 Pro line was the clear victor in the majority of the benchmark tests run by the four sites.
