SSD Performance and
Reliability at HDD Cost
BREAKTHROUGH VALUE ENABLES ALL FLASH ENTERPRISE STORAGE
TO ELIMINATE SPINNING RUST IN DATA CENTERS
Samsung PM1633a solid-state drive offers up to 1,000
times the performance of 15K RPM hard disk drives at
a comparable cost per gigabyte.
Enterprise server and storage administrators face challenging
requirements to deliver mission critical business infrastructure
on a limited budget. Enterprise environments need to deliver
on-premises computing solutions that reliably deliver
predictable performance 24/7, 365 days a year. Considering
each of these factors, IT and data center managers are tasked
with nding optimal storage solutions.
Samsung provides enterprise server and storage
administrators with SSDs that deliver exceptional performance
and reliability in primary enterprise storage applications, such
as virtual desktop infrastructure (VDI), collaboration platforms,
web servers, email, enterprise resource planning, customer
relationship management (CRM), and SQL databases.
Compared to performance HDDs, these high-performing SAS
SSDs deliver up to four times the performance for sequential
workloads, and up to 1,000 times the performance for random
workloads, while still maintaining a comparable cost per
gigabyte. As the pioneer in vertical-NAND (V-NAND) technology,
Samsung has been delivering enterprise grade SSDs based on
cost-effective TLC memory longer than anyone else. Additionally,
Samsung has the advantage of being a ertically integrated
supplier of SSDs, assuring the highest levels of quality.
Samsung PM1633a SAS SSD delivers:
• Consistently High Performance – Up to 1,000 times
the performance of the fastest 15K RPM hard drives,
the Samsung PM1633a SAS SSD provides enterprise
IT administrators performance to spare. An optimized
Samsung native SAS 3.0 controller supplies the drive
with 12 Gb/s of bandwidth and provides enterprises the
performance margin to prevent costly and disruptive
application support tickets.
• Exceptional Value – The same low cost per gigabyte as
slower SAS HDDs. By utilizing Samsung state-of-the-art 3D
V-NAND ash memory, cost effective TLC ash memory can
address high-end enterprise applications, outperforming
older planar MLC ash memory, and providing solid state
performance and reliability at hard drive cost. With no
moving parts, the PM1633a SAS SSD delivers over 10 times
the reliability of spinning disks, reducing the administrative
cost overhead associated with drive replacement.
• Breakthrough Storage Density – Capacities up to 16TB in a
2.5” small form factor (SFF) drive. With 60% higher capacity
per drive, and a smaller 2.5” form factor, up to 384TB can
be stored in a 2U server. This breakthrough in storage
density more than triples the density available with highcapacity HDDs, using an industry standard form factor, and
without sacricing enterprise reliability, availability, and
serviceability (RAS).

SSD Performance and Reliability at HDD Cost
Optimized for enterprise environments
To deliver enterprise reliability and performance, the Samsung
PM1633a uses a native SAS 3.0 controller, supporting dual-port
highavailability needs. To meet the demand for high utilization,
highly virtualized enterprise environments, the PM1633a SAS
SSD utilizes rmware that prioritizes quality of service (QoS)
for sustained random workloads, to keep all virtual machines
running quickly and smoothly. The rmware is also optimized
for always on, always busy workloads ready to respond quickly
to incoming host requests. With no moving parts to fail, the
PM1633a delivers enterprise class reliability for your critical
business data.

With 60% more capacity than today’s highest capacity HDDs,
the PM1633a enables enterprise system administrators to keep
up with the growth of business data, without costly datacenter
expansions. The PM1633a delivers all of this storage capacity
in a compact 2.5” 15mm enterprise form factor, rather than
the bulky 3.5” form factor needed for high-capacity hard
drives. The high capacity PM1633a SSD allows for drive count
consolidation, and provides a critical capability to expand
storage within existing infrastructure, rather than requiring
costly new facilities.

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 PM1633a SAS SSD has been designed to prevent data
loss resulting from unexpected power shutdowns with its power-
loss protection architecture. Upon detection of a power failure,
the SSD immediately uses the stored energy from tantalum
capacitors to provide enough time to transfer the cached data in
DRAM to the ash memory, ensuring no loss of data.
