Enterprise server and storage administrators face challenging requirements
to deliver mission-critical business infrastructure on a limited budget. It is also
imperative these environments remain stable when processing multiple heavy
workloads. Considering each of these factors, IT and data center managers are
tasked with nding high performing and dependable storage solutions.
Samsung provides SSDs with exceptional performance and reliability in primary
enterprise storage applications such as virtual desktop infrastructures, web servers,
email servers, enterprise resource planning, and relational databases.
Compared to performance HDDs, the Samsung PM1643 achieves sequential
workloads up to 6 times faster, thereby reducing the total cost of ownership (TCO).
As the pioneer in vertical-NAND (V-NAND) technology, Samsung has the added
advantage of being a vertically integrated supplier of all its SSD components,
assuring end-to-end integration and superb quality.

Optimized for enterprise environments
To deliver enterprise reliability and performance, Samsung PM1643 uses a native
SAS 3.0 controller, supporting dual-port high availability needs.
To meet the demand of high utilization, highly virtualized enterprise environments,
the PM1643 uses firmware that prioritizes quality of service (QoS) for sustained
random workloads, which keeps virtual machines running quickly and smoothly.
When the majority of mission-critical workloads rely on small-sized random read
(4 KB or less), the PM1643 shows excellent performance to deliver high IOPS. The
firmware is also optimized for always on, always busy workloads, and is ready to
respond quickly to incoming host requests. With no moving parts to fail, the PM1643
delivers enterprise class reliability for critical business data.

BEST-IN-CLASS SAS DRIVE
WITH THE INDUSRTY LARGEST CAPACITY
Built for High-Density Deployments
With over twice the capacity of today’s highest capacity HDDs, the
PM1643 enables enterprise system administrators to keep up with
the growth of business data demands. The PM1643 delivers all
the capacity—up to 30.72 TB—in a compact 2.5” form factor, rather
than the bulky 3.5” form factor needed for high-capacity HDDs. The
combination of a smaller form factor and higher capacity provides the
critical capability to expand storage within existing infrastructure,
rather than requiring costly new facilities.
Samsung PM1643 SAS SSD delivers:
• World’s Largest Storage Density: By tting more memory cells into
a V-NAND chip, the PM1643 provides signicantly more capacity-up
to 30.72 terabytes (TB) in a 2.5” small form factor drive; Up to 737.28
TB can be stored in a 2U server.
• Exceptional Value: Using the latest Samsung 64-layer V-NAND ash
memory, the powerful TLC ash memory employed in the PM1643
can address high-end enterprise applications, outperform planar
MLC ash memory, and provide reliable solid state performance.
• High Performance: The PM1643 provides over 6 times the
sequential read and write performance of the fastest 15K RPM

Operating Temperature
1. Based on the advertised specications of HDD manufacturers as of April 2018.
2. 1 MB = 1,000,000 Bytes, 1 GB = 1,000,000,000 Bytes, 1 TB = 1,000,000,000,000 Bytes, unformatted
capacity. User accessible capacity may vary depending on operating environment and formatting.
3. Performance measured using IOMeter2006 with queue depth 128. Actual performance may vary
depending on use conditions and environment.
4. MTBF is Mean Time Between Failure, and is the predicted elapsed time between inherent failures of a
system during operation.
5. Uncorrectable Bit Error Rate (UBER) is a metric for the rate of occurrence of data errors, equal to the
number of data errors per bits read as specied in the JESD218 document of JEDEC standard.
6. The endurance of SSD in enterprise application is dened as the maximum number of drive writes per
day that can meet the requirements specied in the JESD218 document of JEDEC standard.
7. Active power is measured using IOMeter 2006, Idle power is measured using drive maser 2010.
8. Based on the case temperature which is measured at the hottest point over all case surface. It is
highly recommended to provide sufcient airow to keep SSD working properly within the operating
temperature even on heavier workload.

• Power Efficiency: With no moving parts, the PM1643 achieves up
to 2,000 MB/s sequential write speed at 13.5W power. This equals
about 148 MB/s per watt, which is 4 times more power efcient than
15K RPM HDDs and a 60% improvement from Samsung’s previous
generation PM1633a SAS SSD.
• Long-lasting Reliability: Enhanced software provides metadata
protection as well as data retention and recovery from sudden
power failures; and an error correction code (ECC) algorithm ensures
high reliability and minimal storage maintenance. Also, the PM1643
offers an endurance level of one full drive write per day over a ve-
year warranty period, translating to up to 30.72 TB of data written
every day over ve years without fail. The SSD also provides a mean
time between failure (MTBF) of two million hours.
