Solid State Storage Initiative

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

 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 Specification was developed by the SNIA SSS Technical Work Group (TWG) and defines how to measure SSD performance in a manner that is accurate, repeatable and enables comparison between different manufacturers’ products.

The SSS PTS consists of two separate, precisely targeted specifications for Enterprise and Client.  The specifications are available here.

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

May 26, 2015 - JEDEC Announces Support for NVDIMM Hybrid Memory Modules. JEDEC's JC-45 Committee has approved the first standards for support of “hybrid” DDR4 memory modules which are defined as modules that plug into standard dual in-line memory module (DIMM) sockets and appear like a DDR4 SDRAM to the system controller, yet contain non-volatile (NV) memories such as NAND Flash on the module. Features a quote from the Co-Chairs of the SSSI NVDIMM Special Interest Group.
