HGST leverages decades of proven enterprise storage expertise in Serial Attached SCSI (SAS) 

design, reliability, firmware, customer qualification and system integration to the s842  

solid-state drive (SSD). 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.

In today’s economy, time is money—and accelerating access to data is a proven success 

formula for enterprises and service providers worldwide.

The s842 SAS SSD is purpose-built for enterprise environments, cloud data center servers 

and storage solutions, taking capacity, reliability and endurance to the next level to deliver 

superior application performance for all real-world workloads. With up to 2TB capacity, the 

s842 SSDs offer high capacity in a compact 2.5” SAS enclosure. 

In addition to their world-class performance, the s842 SAS SSD is the most reliable, longest 

lasting SSD solution now available for the enterprise market. Based on fourth-generation 

HGST patented SSD controller technology, the s842 delivers the best performance, endurance 

(i.e., device lifetimes) and reliability that is unmatched in the industry.
