3D V-NAND Technology and
THE SAMSUNG SSD 850 PRO

Samsung's 3D V-NAND flash memory is
fabricated using an innovative vertical
design. Its vertical architecture stacks cell­layers 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 mass­produced 3D V-NAND products for
datacenters which have already been proved
in the market. And Samsung is now
releasing the world’s 1st 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 speed1 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 ten­year 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 hardware­based encryption engine secures your data
with significantly reduced performance
degradation that you may experience with a

performance, based on Samsung’s official specification

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.
