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 new 
Ultrastar® SSD1600MM solid-state drive (SSD) family. The synergistic relationship  
between HGST’s new 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 new Ultrastar SSD1600MM delivers high sequential throughput, up to 1100MB/s read 
and 765MB/s write (12Gb/s SAS). The Ultrastar SSD1600MM 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 new 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 0.44% annual failure rate (AFR) or 
two million hour mean-time-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).
