Solid State Storage Technical Work Group

updated November 2022

The Solid State Storage Technical Work Group (SSS TWG) is creating a reference SNIA architecture to facilitate industry-wide adoption of common requirements, methods, and specifications in related standards organizations.

SSD Performance Specification

The Solid State Storage (SSS) Performance Test Specification defines the test process, thus assuring consistent results and allowing fair product comparisons. To participate in the ongoing work on the spec, join the SSS Technical Work Group, open to SNIA member companies.

Real World Storage Workload Performance Test Specification 

The Real World Storage Workload Performance Test Specification is influenced by many factors, and these factors are quite different than those affecting HDD performance. The unique characteristics of SSDs require that new test methodologies be created, and that traditional metrics be reconsidered. Further, SSD performance is currently being measured in a variety of ways, under a wide range of conditions, making it difficult to directly compare products from different manufacturers. To be successful, the SSD marketplace needs a standard approach to measuring performance that takes into consideration all of the aspects of these NAND Flash-based storage devices.
The SSS TWG has developed a real-world storage workload IO capture, characterization, methodology, test suite and reporting format.  It is intended to provide standardized analysis of in-situ target server application storage performance and standardized comparison and qualification of Datacenter storage when using Reference IO Capture Workloads as the test stimuli in RWSW tests.
