MLC NAND Flash for ultra-high performance and  
The Ultrastar SSD800MH.B 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  
110,000 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 SSD800MH.B family oꢀers signiꢁicant value  
in terms of IOPS per Watt, while reducing total cost  
of ownership (TCO) through low power consumption,  
efficient cooling and reduced space requirements.  
HGST leverages decades of proven enterprise storage  
expertise in Serial Attached SCSI (SAS) design, reliability,  
ꢁirmware, customer qualiꢁication and system integration  
to the Ultrastar® SSD800MH.B solid-state drive (SSD)  
family. The synergistic relationship between HGST’s  
throughput-enhancing SSDs and traditional HDDs  
provides cost eꢀective, 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 Ultrastar SSD800MH.B family combines  
Applications/Environments  
enterprise-grade MLC NAND Flash memory, advanced  
endurance management ꢁirmware and power loss data  
management techniques to extend reliability, endurance  
and sustained performance over the life of the SSD. The  
Ultrastar SSD800MH.B family achieves an extraordinary  
0.35% annual failure rate (AFR) or 2.5 million hour mean-  
time-between-failure (MTBF). The 800GB capacity model  
endures up to 36.5 Petabytes (PB) of random writes  
over the life of the drive—the equivalent of writing 20  
Terabytes (TB) per day for ꢁive years.

HGST Quality and Service  
HGST’s Ultrastar SSD800MH.B 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.  
For complete end-to-end data protection and reliability,  
the Ultrastar SSD800MH.B 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 SSD800MH.B  
family is backed by a ꢁive year limited warranty, or the  
maximum Petabytes (PB) written (based on capacity).
