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.
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 80 MB/s in write speed.
* 850 PRO 128 GB Sequential Write speed: 470 MB/s
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)
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
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.
Protect your PC's hardware and personal data when you take your laptop on the road with the 850 PRO's SED technology. The drive includes an AES-256-bit hardware-based, full disk encryption engine that secures your data without performance degradation, often experienced with software-based encryption.
The 850 PRO's advanced security complies with the TCG™ Opal v2.0 standards, protecting PSID, and is compatible with the Microsoft® eDrive IEEE® 1667 protocol. Plus, you can erase or initialize data with the crypto erase service.
The 850 PRO includes Dynamic Thermal Guard protection, which keeps your PC performance safe from overheating. Dynamic Thermal Guard protection monitors and maintains the drive's optimal operating temperature with a throttle feature that automatically drops the SSD's temperature when necessary to protect your data and ensure the responsiveness you expect.
Using its One-stop Install Navigator software, you can migrate all the data and applications from your SSD or HDD to the 850 PRO quickly and easily. The Auto Install guide navigates you through the simple three-step process.
Plus, you can conveniently monitor, manage and maintain your 850 PRO with the Samsung Magician software, which features tools to help you maximize performance, including benchmarking, advanced OS optimization, disk health status tracking and over-provisioning (OP) settings.
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.
