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® SSD1600MR 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.

The new Ultrastar SSD1600MR delivers high sequential throughput, up to 1100MB/s read 

and 700MB/s write (12Gb/s SAS). The Ultrastar SSD1600MR also delivers up to 130,000 

read and 30,000 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 SSD1600MR 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 SSD1600MR 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 SSD1600MR 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 5.8 Petabytes (PB) of random writes over the life of the drive—the equivalent of 
writing 3.2 Terabytes (TB) per day for five years.

For complete end-to-end data protection and reliability, the Ultrastar SSD1600MR 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 SSD1600MR family is backed by a 
five year limited warranty, or the maximum Petabytes (PB) written (based on capacity).
