SAS DATA CENTER S SD
Maximize Storage and Server Scalability with SAS SSDs
Data is transforming the world and growing at an exponential pace. The SAS interface
continues its dominance in traditional enterprise storage arrays, making the everincreasing volume of data rapidly and reliably available. Storage solutions depend on
SAS’s protection features, such as dual-port failover for redundancy, and SAS’s high
reliability to power mission-critical applications such as ERP, OLTP, OLAP, and more.
Designed with a dual-port 12Gb/s SAS interface for seamless integration into enterprise
environments, the Ultrastar® DC SS530 SAS SSD is available in capacities from 400GB to
15.36TB, double the capacity of prior generations. Delivering performance up to 440,000
random read and 320,000 random write IOPS—best in class among current 12Gb/s
SAS SSDs—the Ultrastar DC SS530 can help to drive faster data analytics, drive higher
productivity, and power business decision-making.
Proven Architecture with Industry-Leading Quality
and Reliability
Ultrastar DC SS530 leverages the proven architecture of the prior generation Ultrastar
SS300 with second generation 3D TLC NAND flash memory. The Ultrastar DC SS530
achieves an extraordinary 0.35% annual failure rate (AFR) or 2.5 million hours mean-timebetween-failure (MTBF). DC SS530 offers three endurance options of 1, 3 and 10 drive
writes per day (DW/D) to meet the most stringent data center requirements.
Help keep confidential data secure by deploying self-encrypting drive technology that
supports Trusted Computing Group (TCG) Enterprise standards for security services
and FIPS 140–2 validation for cryptographic-enabled drives that are required for cer tain
government applications. The Ultrastar DC SS530 is backed by a five-year limited warranty
or the maximum petabytes (PB) written (based on capacity), whichever comes first.
Trust Your Storage Systems with SSD Products
Developed by Experts in Enterprise Storage
Ultrastar SAS SSDs leverage decades of proven enterprise storage expertise in Serial
Attached SCSI (SAS) design, reliability, firmware, customer qualification, and system
integration. The synergistic relationship between the new throughput-enhancing SSDs
and traditional HDDs provides cost-effective, end-to-end enterprise-class storage
options that deliver reliability, compatibility, capacity, cost savings, and system
performance. This combination makes Ultrastar storage drives an ideal choice to help
meet escalating reliability, endurance, and performance requirements in the most
demanding data center environments.
