Samsung 850 PRO Solid State Drives

- Replaces the Samsung 840 PRO Solid State Drives- Replaced by the Samsung 860 PRO Solid State Drives

With 150TB Total Bytes Written on a 10-year limited warranty, the SSD 850 PRO is at the top of its class. Add to that long-term reliability and unbeatable performance, and the choice is clear.


  1. Fabricated using an innovative 3D V-NAND architecture
  2. Outperforms similar models on the market by more than 100 MB/s in write speed
  3. Provides 1.8 times faster performance in the RAPID mode
  4. Safeguard precious data without sacrificing performance
  5. Massive 10 year limited warranty

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.

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.

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.

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 milliwatts 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.

Safeguard precious data without sacrificing performance

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 initialise data with the crypto erase service.

Protect your PC from overheating with Dynamic Thermal Guard protection

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.

Level up to the 850 PRO simply without any hassle

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 maximise performance, including benchmarking, advanced OS optimisation, disk health status tracking and over-provisioning (OP) settings.

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.
