V-NAND Technology and THE
SAMSUNG SSD 850 EVO

Samsung’s unique and innovative V-NAND
flash memory architecture is a breakthrough
in overcoming the density limitations,
performance and endurance of today’s
conventional planar NAND architecture. V­NAND is fabricated by stacking cell layers
vertically over one another rather than
decreasing the cells dimensions and trying
to fit itself onto a fixed horizontal space
resulting in higher density and better
performance utilizing a smaller footprint.

The 850 EVO is the advanced consumer

SSD powered by V-NAND technology that
maximizes everyday computing experiences
with optimized performance and enhanced
reliability.

Optimized performance for
everyday computing
experiences

Powered by Samsung's cutting-edge V-NAND
technology, 850 EVO delivers top-class
sequential and random read and write
performance to optimize everyday computing.
With improved performance thanks to
TurboWrite technology the 850 EVO provides
not only more than a 10% better user
experience than 840 EVO but up to 1.9x faster
random write speeds for the 120/250 GB
models as well. In fact, the 850 EVO delivers
top class sequential read (540 MB/s) and write
(520 MB/s) performance in all capacities. This
comes with optimized random read and write
performance on all QD and improved QD1 and
QD2 random performance for Client PC usage.

Reinforcement of TurboWrite
Technology

In the early stages of the 840 EVO, Samsung
adopted sequential write performance first.
With TurboWrite, write speeds are significantly
accelerated during data transfers by creating a
high-performance write buffer in the SSD. If a
consecutive write operation (i.e. no idle time)
exceeds the size of the buffer, the transfer will
exit TurboWrite and be processed at ”After
TurboWrite” speeds. Once the buffer is cleared,
TurboWrite performance will resume. However,
the buffer size for TurboWrite is more than
sufficient for everyday PC use, and you should
experience accelerated speeds for most
workloads.

For the 850 EVO, enhanced TurboWrite
technology applied to random write speeds up
to 1.9x faster for the 120 GB model and 1.25x
faster for the 250GB model over the 840 EVO.

Guaranteed endurance and
reliability for maximum use

Guaranteed endurance

The 850 EVO delivers guaranteed endurance
and reliability by doubling the Tera bytes
Written(TBW) compared to the previous
generation 840 EVO backed by an industry
leading 5 year warranty.

With twice the endurance of a typical NAND
flash SSD, the 850 EVO will keep working as
long as you do. The 850 EVO guarantees a 5
year limited warranty or 75TBW for 120GB,
250GB, 150TBW for 500GB, 1TB and 300TBW
for 2TB and 4TB.

Enhanced reliability with improved
sustained performance

With enhanced reliability through improved
sustained performance, the 850 EVO assures
long-term dependable performance up to 30%
longer than the 840 EVO with minimized
performance degradation. This means you can
use it every day when taking care of work or
entertaining yourself knowing it will keep
performing even with heavy daily workloads
over the years.

Advanced data encryption

The 850 EVO provides the same data
encryption feature as the 840 EVO does. Self­Encrypting Drive (SED) security technology
will help keep data safe at all times. It includes
an AES 256-bit hardware-based encryption
engine to ensure that your personal files
remain secure. Being hardware-based, the
encryption engine secures your data without
performance degradation that you may
experience with a software-based encryption.
Also, 850 EVO is compliant with advanced
security management solutions (TCG Opal and
IEEE 1667). Magician will guide ”How to use
security features”. Furthermore, you can erase
or initialize data with the crypto erase service
with PSID.

Efficient power management
for all PC applications

Power consumption affects everyone. You
actually save of up to 50% more on power than
with the 840 EVO during write operations
thanks to V-NAND consuming half the power
of 2D planar NAND.

Plus, whether it’s preserving battery life for
longer cordless use or just saving on costs,
power management is important. Device sleep
signals the SSD to enter a low power state
which is vital for ultra-books and other battery
powered devices. With 850 EVO’s Device Sleep
at a highly efficient 2mW you get longer
battery life on your notebook thanks to a
controller optimized for V-NAND. With the 850
EVO you can work and play longer without
having to plug in.
