Unrivaled Performance
The Samsung SSD 840 PRO is a high-performance
SSD designed for power users. Capable of
delivering up to 100,000 IOPS Random Read
Speed and 540MB/s Sequential Read Speed, it is
an SSD of unrivaled high performance. Even better,
the advanced MDX controller delivers these speeds
regardless of data type, unlike some competing
controllers that greatly favor compressible data.
Superior Reliability
As the world’s #1 DRAM, NAND Flash, and SSD
supplier, Samsung has unique, industry-leading
engineering resources, technologies, and
manufacturing processes as well as more stringent
quality and testing standards. All Samsung SSDs
are designed and built completely in-house, rather
than sourcing generic parts from the market. The
Samsung SSD 840 PRO Series is optimized for
exceptional, sustained performance and unrivaled
reliability through its specially-engineered wear-
leveling and garbage collection algorithms and is
backed by a generous 5-year limited warranty.
Performance Sustainability
The Samsung SSD 840 PRO provides the same
excellent performance throughout its entire
lifetime and under extremely heavy workloads. In
fact, the sophisticated MDX controller is capable of
maintaining peak performance under punishing
conditions for more than twice as long as the
nearest competitor.

Business Friendly Features
The 840 PRO Series SSD introduces three
important hardware features for businesses:
Worldwide Name (WWN), LED Indicator support,
and hardware-based AES 256-bit Full Disk
Encryption (FDE). The first two of these features
make it easier to integrate the 840 PRO SSD into
server and storage systems. The third, hardware-
based AES Encryption, helps safeguard data
against attack by encrypting all information on the
disk at the hardware level, which means there is no
detrimental effect on performance. Because the
encryption key is stored on the drive itself, it is not
at risk of interception or outside attack, even if the
drive is placed into a new PC. Also, destroying data
is as easy as performing a Secure Erase using the
Magician software.
In additional to the hardware features mentioned
above, Samsung’s Magician software is being
completely redesigned and will include several
business-friendly new features when version 4.0
becomes available later this year. With the addition
of Drive Health Status, Total Bytes Written (TBW),
and Disk Scan & Error Reporting functionality, it will
be much easier for IT managers to monitor drive
health and plan hardware replacement cycles.
