Western Digital Introduces New Dual-Port SAS SSD for Servers and Storage Arrays with Best-in-Class Performance

Share:

New Ultrastar® DC SS530 SAS SSD delivers
improved power efficiency, double the storage capacity, and
best-in-class performance for mission-critical applications

Western Digital Corporation (NASDAQ:WDC), a data technology leader,
today introduced the new Ultrastar DC SS530 SAS SSD, the company's
highest-density drive and the fastest dual-port SAS SSD in the market¹,
enabling server and storage array manufacturers to offer customers
substantially lower data center TCO for Fast Data applications. By
doubling maximum capacity of the previous generation to 15.36TB within
the same 2.5-inch 15-mm form factor, drive storage density also doubles,
giving IT managers the potential to reduce the number of drives
deployed, consolidate servers and open up valuable rack space for
improved CapEx and OpEx costs.

Developed in partnership with Intel®, the Ultrastar DC
SS530 is based on a trusted third-generation platform that has been
previously qualified at most major OEMs worldwide. It offers consistent
performance and reliability to meet the rigorous demands of today's
toughest data center workloads. Designed with a 12Gb/s SAS interface,
and available in capacities from 400GB to 15.36TB, the Ultrastar DC
SS530 delivers up to 440,000 random read and 320,000 random write IOPS —
providing rapid access to "hot" enterprise data for higher productivity
and operational efficiency.

"Our proven history has garnered trust from leading server and storage
system providers around the world. Through these partnerships we have
deep expertise in tiered storage needs as well as the importance of
delivering the highest reliability, cost-efficiency and ease of system
integration," said Ulrich Hansen, vice president of Enterprise Product
Management at Western Digital. "With the Ultrastar DC SS530, we are
releasing another high-quality product designed to meet the needs of our
customers. Built on 64L 3D TLC NAND, the Ultrastar SS530 delivers
important advances in performance and power efficiency. Combining these
improvements with the reliability that our Ultrastar drives have become
known to represent significantly enhances the value we deliver to the
market."

"For the past decade, our partnership with Western Digital has resulted
in producing world-class SAS solutions, and this new Ultrastar SAS SSD
is no different," said Bill Leszinske, vice president of strategic
planning, marketing and business development at Intel Corporation.
"Using Intel technology, Western Digital is able to deliver new
improvements and features for their SAS SSD product line that will help
their enterprise customers meet the demands for reliability, capacity
and performance while reducing space, power and cooling costs."

Additional Ultrastar DC SS530 features and specifications:

  • Supports a wide range of workloads with three endurance options: 1, 3
    and 10 DW/D
  • Provides flexibility to tune performance and power efficiency with
    three power modes: 9, 11 and 14 Watts
  • Helps protect data from unauthorized use and enables swift repurpose
    or retirement of drives with security options, including Secure Erase
    (SE), Instant-Secure Erase (ISE) and Self-Encrypting Drive (TCG SED).
    Models with TCG SED plus FIPS 140-2 validation are expected to be
    available in Q4 2018.

Western Digital is currently shipping Ultrastar DC SS530 samples to
select OEM customers with broader availability later this quarter. The
new drive further expands Western Digital's broad range of
enterprise-class storage solutions, which include high-performance NVMe™
SSD devices, innovative HelioSeal® enterprise hard disk
drives as well as SAS and SATA SSD devices, IntelliFlash™ all-flash
arrays, ActiveScale™ object storage systems, and Ultrastar storage
servers and platforms.
