When today’s “new normal” requires doing more with less, the HGST s1122 PCIe accelerator more 

than meets the challenge. Enterprise data centers and cloud computing environments demand 

high density, high-performance servers to ensure consistent levels of application performance 

and compliance with Service Level Agreements. 

HGST’s s1122 PCIe accelerator improves access to data in server and storage applications—

including virtualized environments, Web serving and hosting, and database deployments 

such as SQL Server, Oracle and In-Memory Computing. This accelerates performance in 

enterprise data centers and cloud computing applications, as well as Web 2.0 and social media 

environments. Built on fourth-generation SSD controller technology, the s1122 PCIe accelerator 

is an enterprise-class solution that delivers low latency, high performance and enterprise-class 

reliability.

In addition to its low latency and high-performance capabilities, the s1122 PCIe accelerator 

integrates HGST’s industry-leading CellCare®, Secure Array of Flash Elements™ (SAFE) and 

PowerSafe® technologies into an ASIC-based SSD controller to provide an unparalleled 

combination of endurance and data protection for mission-critical enterprise and cloud 

computing applications. 

The s1122 PCIe accelerator is custom-engineered to meet the demands of enterprise data 

centers and cloud computing applications, delivering higher transaction rates that support 

demanding applications and designs while reducing footprint and power consumption. 

Time is money in these service-intensive environments, and the s1122 PCIe accelerator 

speeds up server performance without consuming server CPU and memory resources. This 

enables data centers to deploy fewer and lower cost servers for enhanced application-level 
acceleration and data center consolidation.
