Ultrastar SS300


Increase Productivity and Operational Efficiency by Boosting IOPS Performance with SAS SSDs
As data centers and enterprises struggle to manage the growing abundance and availability of data, the next generation of SAS SSDs with enhanced performance and endurance arrives to help address data access challenges. The Ultrastar® SS300 solid-state drive (SSD) is offered in a 2.5-inch small form factor that delivers ultra-high performance to power through the most challenging workloads.

Designed with a 12Gb/s SAS interface for seamless integration into enterprise environments, the Ultrastar SS300 delivers high sequential throughput, up to 2100MB/s read at 14W power. Available with capacities from 7.68TB to 400GB, the SS300 delivers up to 400,000 read and 200,000 write IOPS—double the speed of current 12Gb/s SSDs—providing rapid access to “hot” enterprise data for higher productivity and operational efficiency. The Ultrastar SS300 family offers significant value in terms of IOPS per Watt, reducing total cost of ownership (TCO) through low power consumption, efficient cooling and reduced space requirements.

Data Durability and Security with Industry-Leading Quality and Reliability
Ultrastar SS300 combines enterprise-grade 3D MLC or TLC NAND flash memory, advanced endurance management firmware and power loss data management techniques to extend reliability, endurance, and sustained performance over the life of the SSD. The Ultrastar SS300 family achieves an extraordinary 0.35% annual failure rate (AFR) or 2.5 million hours mean-timebetween-failure (MTBF). The 3.2TB 10 DW/D capacity Ultrastar SSD endures up to 59 petabytes (PB) of random writes over the life of the drive—the equivalent of writing 16 terabytes (TB) per day for five years.

For complete end-to-end data protection and reliability, the Ultrastar SS300 family incorporates the T10 Data Integrity Field (DIF) standard, extended error correction code (ECC), ExclusiveOR (XOR) parity to protect against flash die failure, parity-checked internal data paths without an external write cache, and an exclusive power loss data management feature that does not require supercapacitors. The Ultrastar SS300 family 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
The HGST brand leverages decades of proven enterprise storage expertise in Serial Attached SCSI (SAS) design, reliability, firmware, customer qualification and system integration to the Ultrastar SS300 family. The synergistic relationship between the new throughput-enhancing SSDs and traditional HDDs provides cost effective, end-to-end enterprise-class storage options, delivering reliability, compatibility, capacity, cost and system performance. This combination makes HGST-brand storage drives an ideal choice to help meet escalating reliability, endurance, and performance in the most demanding enterprise environments.
