3D V-NAND Technology andTHE SAMSUNG SSD 850 PRO

Samsung's 3D V-NAND flash memory is fabricated using an innovative vertical design. Its vertical architecture stacks cell-layers on top of one another rather than trying to decrease the cells' length and width to fit today's ever-shrinking form factors. This architecture results in higher

density and better performance using a smaller footprint. Samsung's 3D V-NAND technology is a breakthrough in overcoming the density limits currently faced with the conventional planar NAND architecture.

The Samsung SSD 850 PRO is a brand new successor of the 840 PRO, Samsung's premium SSD product. The 850 PRO is powered by Samsung's 3D V-NAND technology. In 2013, Samsung mass-produced 3D V-NAND products for datacenters which have already been proved in the market. And Samsung is now releasing the world's 1^st 3D V-NAND SSD for client PCs.

Ultimate Read/Write Performance

Powered by Samsung's own cutting-edge 3D V-NAND technology, the 850 PRO delivers

up to twice the write speed ^1 than that of the traditional 2D planar NAND flash for ultimate read and write performance. By changing to the layer cylindrical cell structure, more cells can be stacked vertically, resulting in smaller footprint and higher density. As a result, you gain superior maximum read and write performance in both sequential and random aspects, especially with the 128GB model that outperforms other similar models in the market by more than 100MB/s in write speed.

Plus, with RAPID (Real-time Accelerated Processing of I/O Data) mode, you can boost its optional higher speeds - up to almost twice faster write performance speeds than those of the previous model. ^2 The Magician software allows you to enhance performance by processing data on a system level using free PC memory (DRAM) as a cache.

Enhanced Endurance and Reliability

Enhanced Endurance

Samsung's 3D V-NAND technology is built to handle 150 Tera Bytes Written (TBW) for 128GB and 256GB, 300 TBW for 512GB and 1TB, 450TBW for 2TB and 600TBW for 4TB. Plus, it comes with an industry-leading ten-year limited warranty.

Advanced Data Encryption

The 850 PRO provides the same data encryption features as the 840 EVO does. The Self-Encrypting Drive (SED) security technology will help keep your data safe. It includes an AES 256-bit hardware-based encryption engine to ensure that your personal files remain secure. A hardware-based encryption engine secures your data with significantly reduced performance degradation that you may experience with a software-based encryption. Also, the 850 PRO is compliant with advanced security management solutions (TCG Opal and IEEE 1667). Magician will guide you through the security features. Furthermore, users can delete or initialize data with the crypto erase service with PSID.

Efficient Power Management

Less Power Consumption for Active and Stand-by States

Even with all of the above performance improvements, the use of the new technology of 3D V-NAND have enabled us to make the 850 PRO as one of the most energy-efficient drives on the market. Its idle power is almost the same as the 840 PRO's and its active (average) write power has been dramatically reduced up to 40% in comparison to the 840 PRO's due to the 3D V-NAND technology.
