DC SS200
Easily Scale Enterprise Flash Storage with
Workload-Optimized SAS SSDs
Leveraging widely deployed SAS storage infrastructure to scale out enterprise flash is
critical for budget-conscious data centers trying to keep pace with an ever increasing
volume and velocity of data generated daily. The Ultrastar® DC SS200* solid state drive
(SSD) is a 12Gb/s SAS Enterprise SSD that helps transform hybrid and all-flash data
centers by scaling flash storage capacities using workload-optimized solutions to deliver
exceptional value.
Data center managers can target performance acceleration of mixed-use application
workloads such as Online Transaction Processing (OLTP) or push the capacity envelope

Delivering High Capacity, High Performance SAS
SSD with Cost-Effectiveness and Data Reliability
Ultrastar DC SS200 SSDs integrate Western Digital 15nm NAND and the enterprise-tested
Guardian Technology™ platform to deliver enterprise-grade reliability, endurance and
performance. Delivering up to 1,800MB/s and 250,000 4KiB IOPS read performance
combined with exceptional write performance, DC SS200 enables valuable application
acceleration without compromise. With significantly improved performance consistency
and associated Quality of Service (QoS) metrics, this generation of SAS SSDs can help
meet stringent enterprise application service level agreements (SLAs).
Available in capacity points from 400GB to 7.68TB, Ultrastar DC SS200 SSDs also offer a
choice of endurance options of either 3 random drive writes per day (DW/D) for mixeduse workloads or 1 random DW/D for read-intensive workloads. All drives support the
DW/D endurance rating over a 5-year limited warranty.
Proven Provider of Enterprise-Grade SSD Products
Ultrastar SSDs leverage decades of proven enterprise storage expertise in Serial Attached
SCSI (SAS) design, reliability, firmware, customer qualification and system integration to
this key member of the Ultrastar line-up.
The Ultrastar DC SS200 SAS SSD is protected by the Guardian Technology™ platform, a
comprehensive suite of enterprise features comprised of FlashGuard™, DataGuard™ and
EverGuard™ technologies.
• FlashGuard technology combines aggregated flash management and advanced signal
processing to reliably extract significantly more life from commercial-grade MLC flash
for read-intensive application workloads.
• DataGuard technology features full data path protection, to help safeguard user data
from corruption along all data paths in the SSD.
• Ever Guard technology helps protect against loss of user data in the event of
unexpected power interruptions using a third-generation backup power circuit design
and high reliability discrete capacitors.
