Ultrastar SSD1600MM

HGST Enterprise Storage Experience
HGST leverages decades of proven enterprise storage expertise in Serial Attached SCSI (SAS) design, reliability, firmware, customer qualification and system integration to the Ultrastar® SSD1600MM solid-state drive (SSD) family. The synergistic relationship between HGST’s throughput-enhancing SSDs and traditional HDDs provides cost effective, end-to-end enterprise-class storage solutions, delivering reliability, compatibility, capacity, cost and system performance. This combination makes HGST a leading SSD/HDD provider with the experience and technology needed to meet escalating reliability, endurance and performance in the most demanding enterprise environments.

Maximum Performance, Reliability and Endurance
The Ultrastar SSD1600MM delivers high sequential throughput, up to 1100MB/s read and 765MB/s write (12Gb/s SAS). It also delivers up to 130,000 read and 100,000 write IOPS, reaching speeds >100 times faster than HDDs and double the speed of current 6Gb/s SSDs, allowing rapid access to “hot” enterprise data for improved productivity and operational efficiency. The Ultrastar SSD1600MM family offers significant value in terms of IOPS per Watt, while reducing total cost of ownership (TCO) through low power consumption, efficient cooling and reduced space requirements.

The Ultrastar SSD1600MM family combines enterprise-grade MLC 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 SSD1600MM family achieves an extraordinary 0.35% annual failure rate (AFR) or 2.5 million hour meantime-between-failure (MTBF). The 1600GB capacity model endures up to 29.2 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 SSD1600MM family incorporates the T10 Data Integrity Field (DIF) standard, extended error correction code (ECC), Exclusive-OR (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 SSD1600MM family is backed by a five year limited warranty, or the maximum Petabytes (PB) written (based on capacity).

HGST Quality and Service
HGST’s Ultrastar SSD1600MM family extends the company’s long-standing tradition of performance and reliability leadership. A balanced combination of new and proven technologies enables high reliability and availability to customer data. HGST drives are backed by an array of technical support and services, which may include customer and integration assistance. HGST is dedicated to providing a complete portfolio of SSD/HDD solutions to satisfy today’s monumental computing needs.
