Ultrastar® SS200
SAS Enterprise Solid State Drives

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® SS200 solid state drive (SSD) is a 12Gb/s SAS Enterprise SSD from HGST 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 on read-intensive workloads like data warehousing and corporate file servers. HGST continues to build on its strong tradition of leading-edge SAS SSD products to deliver more capacity, improved performance and continued emphasis on reliability to enable universal flash adoption in enterprise storage.

HGST Delivers High Capacity, High Performance SAS SSD with Cost-Effectiveness and Data Reliability
Ultrastar SS200 SSDs integrate SanDisk-brand 15nm NAND and the enterprisetested 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, the drive 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 SS200 SSDs also offer a choice of endurance options of either 3 random drive writes per day (DW/D) for mixed-use workloads or 1 random DW/D for read-intensive workloads.

Proven Provider of Enterprise-Grade SSD Products
HGST leverages decades of proven enterprise storage expertise in Serial Attached SCSI (SAS) design, reliability, firmware, customer qualification and system integration to this newest addition to the Ultrastar line-up.

The Ultrastar SS200 SSD is powered 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.
  • EverGuard 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.
