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 ever-increasing 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.
Ultrastar® DC SS540, Western Digital’s 6th generation of SAS SSD drive, delivers performance to data centers with 96-layer 3D NAND technology and a proven track record of reliability. Designed with a dual-port 12Gb/s SAS interface for seamless integration into data center
environments, the Ultrastar DC SS540 SAS SSD is available in capacities from 800GB to 15.36TB. Achieving exceptional performance by delivering up to 470K/240K Random Read/Random Write IOPS, the DC SS540 offers the best value for data centers by providing dual/single port support, desired features, power options, multiple endurance SKUs and mainstream capacities. It is ideal for ultra high-performance tier-0 enterprise storage, high performance computing (HPC), and software-defined storage (SDS).

Proven Architecture with Industry-Leading Quality and
Ultrastar DC SS540, with 96-layer 3D TLC NAND flash, leverages the proven architecture of the prior generations of SAS to achieve an extraordinary 0.35% annual failure rate (AFR) or 2.5 million hours mean-time-between-failure (MTBF). DC SS540 offers two endurance options of 1 and 3 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 certain government applications. The Ultrastar DC SS540 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 to provide end-to-end data protection storage for data centers. The synergistic relationship
between throughput-enhancing SSDs and traditional HDDs provides cost-effective option that delivers reliability, compatibility, capacity, cost savings, and system performance. Ultrastar SAS SSD drives are the ideal choice to help meet escalating reliability, endurance, and performance requirements in the most demanding data center environments.
