Product Brief
EXTREME PERFORMANCE FROM THE SSD TECHNOLOGY LEADER
Maximize your data transmission with Samsung’s highly reliable, high
performance PM1725b SSD
Enterprise environments have unique requirements to ensure that they operate optimally
24/7, 365 days a year. Varied levels of performance with low latency is essential. It is also
critical that these environments remain stable when processing a wide variety of read and
write workloads. The most crucial criteria of all is protection from data corruption or loss due
to unexpected power outages. Considering each of these factors, IT and data center managers
are tasked with finding high performing and dependable memory solutions.
Samsung is offering enterprises superb solid-state drives (SSDs) that deliver outstanding
performance in multi-thread applications, such as compute and virtualization, relational
databases and storage. These SSDs are also extraordinarily reliable for continuous operation
regardless of unanticipated power loss. Using proven expertise and a wealth of experience in
cutting-edge SSD technology, Samsung memory solutions help data centers operate
continuously at the highest performance levels. Samsung has the added advantage of being
the sole manufacturer of all of its SSD components, ensuring end-to-end integration,
remarkable quality assurance and the utmost compatibility.
Samsung PM1725b Performance vs Enterprise SAS
•
High capacities
The 1725b supports a range of
capacities, from 1.6TB to an industry
leading 15.36TB.
The NVMe advantage
The NVMe protocol was built from
the ground up to maximize flash
storage performance and minimize
latency. It replaces legacy diskbased protocols and uses the PCIe
interface to enable higher
bandwidth.

Samsung PM1725b NVMe SSD
Realize extreme performance with ultra-low
latency in read-intensive applications
To satisfy an enterprise environment’s exceptionally highdemands, an SSD must perform over long periods of time at
maximum performance levels for the variety of workloads
accessing the device simultaneously. In addition, the SSD must
provide the performance consistency to satisfy grueling Quality
of Service (QoS) requirements.
Delivering highly optimized performance for
various data center applications
The Samsung PM1725b SSD is optimized to excel in virtually any
data center scenario. This enterprise-level, ultra-high
performance SSD provides exceptional random read
performance and is particularly suitable for read-intensive data
center applications.
Physical and Digital Flexibility to fit your needs
The PM1725b is available in both 2.5" U.2 and HHHL AIC form
factors. In addition, the PM1725b firmware can be modified by
the user to exchange some endurance for additional drive
capacity. These features provide you with the flexibility to bring
top-tier performance and reliability to a variety of
architectures and environments.
Enterprise-grade power loss protection
During normal power-off periods, the host server allocates time
to preserve data integrity by transmitting a standby command to
each device. In the event of an unexpected power loss,
though,
the cached data in a storage device’s internal buffers (DRAM) can
be lost. This can occur with unexpected power outages, or when
users unplug devices from the system. However, the Samsung
PM1725b SSD has been designed to prevent data loss resulting
from unexpected power shutdowns with its power-loss
protection architecture. Upon detection of a failure, the SSD
immediately uses the stored energy from tantalum capacitors to
provide enough time to transfer the cached data in DRAM to the
flash memory, ensuring no loss of data.

can also be reconfigured as capacity optimized, changing to 1
DWPD at 1.92TB, 3.84TB, 7.68TB, and 15.36TB. The capacity
optimized version is most popular when utilizing dual port
functionality in all-flash-array applications.
Delivering Dual-Port NVMe to the Enterprise
PM1725b supports dual-port functionality, enabling highavailability via two access paths to the storage array
controller. This feature delivers the reliability, availability and
serviceability (RAS) that is required for enterprise storage
designs, allowing for SAS SSDs to be replaced by highperformance NVMe SSDs in new all-flash-array architectures.
