The world's first 3D Vertical NAND
Samsung SSD 850 PRO
What is V-NAND and how does it differ from existing technology?
Samsung's flash memory is fabricated using an innovative 3D V-NAND architecture, which stacks 32 cell layers on top of one another rather than trying to decrease the cells' length and width to fit today's shrinking form factors. The result is higher density and higher performance using a smaller footprint and a breakthrough in overcoming the density limits of conventional planar NAND architecture.
Boost performance with an industry-leading 3D V-NAND SSD
Powered by Samsung's cutting-edge 3D V-NAND technology, the NAND flash memory delivers the ultimate in read and write performance in both sequential and random aspects. This is especially impressive in the 128 GB model* that outperforms similar models on the market by more than 100 MB/s in write speed.
* 850 PRO 128 GB Sequential Write speed: 470 MB/s
Shift into high gear with the enhanced RAPID mode
You can kick up the read/write performance on every capacity when you need it with the RAPID mode. Just like shifting gears in a car, Magician software gives you the option to enhance performance by processing data on a system level using free PC memory (DRAM) as a cache, providing 1.8 times faster performance in the RAPID mode*.
* PCMark Vantage score (512 GB): 53K > 97K(in RAPID mode)
An SSD that won't quit before you do
With twice the endurance of the previous model*, the 850 PRO will keep working as long as you do. Samsung's V-NAND technology is built to handle 150 Terabytes Written (TBW) which equates to a 40 GB daily read/write workload over a 10-year period. Plus, it comes with the industry's top-level ten-year limited warranty.
* 840 PRO: 73 TBW > 850 PRO: 150 TBW
Work longer with high-efficiency innovation
The efficient, power management components in the 850 PRO enable you work longer and more productively. Boasting the lowest power consumption of any SSD when in full use, the 850 PRO expends less energy while maintaining market-leading performance. The 850 PRO fully supports the sleep mode on the Ultrabook™, consuming only 2 m watts of power. Plus, its LPDDR2 cache memory provides higher performance while consuming 30 percent less power when active and 93 percent less power when idle than typical DDR2 or DDR3 memory.
Ensure each component works together seamlessly
Samsung is one of the few manufacturers that actually design all the SSD components in-house and has the most experience in the SSD market. Because Samsung has intimate knowledge of every component and its parts, it can fine-tune them at each stage of development to ensure they work together beautifully. The result – enhanced performance, lower power consumption with an up to 1 GB LPDDR2 DRAM cache memory and improved energy-efficiency with the 3-core MEX controller.
