Solid State Storage Initiative

Welcome to the Solid State Storage Initiative (SSSI), dedicated to fostering the acceptance and growth of Solid State Storage (SSS) and Persistent Memory in the marketplace.  To achieve those goals, SSSI provides education, performs market outreach, and influences/promotes standards. Learn more in the SSSI Brochure and NVDIMM Infographic.

SSSI member companies collaborate in the areas of Persistent Memory, Performance, and PCIe SSD.  Read on to learn more!

Persistent Memory

Jim Pappas, SNIA Vice-Chairman and co-chair of the SNIA Solid State Storage Initiative, encapsulates what persistent memory will mean to consumers and the industry in this excellent interview.

SNIA's leadership in Persistent Memory is captured on the SNIA Persistent Memory webpage.  SNIA shares their knowledge with the industry via the SNIA Persistent Memory Summit held each January, demonstrations and sessions in leading conferences, around the world, development of specifications, and contributions to standards. Presentations and videos from the latest 2018 Summit are now available, access them HERE.  

Persistent Memory and NVDIMM SIG

A Non-Volatile Dual In-line Memory Module (NVDIMM) operates from DRAM with Flash as backup to create a high performance non-volatile storage device that plugs directly into the memory bus.  The SNIA Persistent Memory and NVDIMM Special Interest Group (SIG) is shepherding this technology into the marketplace, and providing to member companies an organization focused on accelerating the awareness and adoption of Persistent Memories and NVDIMMs for competing architectures.   Their latest activities are a SNIA Tutorial, the NVDIMM Cookbook, and NVDIMM webcasts.


Non-Volatile Memory (NVM) features and performance are outgrowing the existing storage model.  NVM is evolving to be less like storage, more like memory.  The SNIA NVM Programming Model, developed by the NVM Programming TWG, defines new software programming models for NVM.   The model describes extensions allowing software to utilize NVM features and enables designers to develop APIs that take advantage of NVM features and performance. 

A SNIA Technical Whitepaper, NVM PM Remote Access for High Availability, explores the requirements that High Availability extensions to the NVM.PM.FILE mode of the SNIA NVM Programming Model might place on high speed networking, such as RDMA.  Download this paper, and other SNIA Technical Activities Whitepapers, here.





SSSI is leading the way in understanding and quantifying SSS performance.

SSDs behave very differently than HDDs, and standard HDD benchmarks will not provide a true picture of SSD performance. 

SSSI has developed substantial expertise in the area of SSD performance and behavior.  The SSS Performance Test Specifications were developed by the SNIA SSS Technical Work Group (TWG) and define how to measure SSD performance in a manner that is accurate, repeatable and enables comparison between different manufacturers’ products. 

Testing is done frequently using the SSS Performance Test Specifications.  The latest results are shown in the chart above, and the chart can be downloaded here.

Learn more about the SSD Performance Project here.

The SSS System TWG, building on the work of the SSS TWG, is developing a specification for measuring the performance of SSS systems.

A testing service based on the SSS Performance Test Specification is available.  Details on the service are available here



PCI Express (PCIe), the ubiquitous system bus, has evolved to become a storage device interface.  SSDs are able to take advantage of the high bandwidth of PCIe and are available in multiple form-factors.  The SSSI PCIe SSD committee provides guidance to the marketplace on PCIe SSDs. They also coordinate with other industry organizations involved in PCIe SSD activities to access additional expertise and to provide a broader industry perspective for our members.
