Commonly used SSD test software include CDM, AS SSD Benchmark, ATTO Disk Benchmark, IOMeter, and PCMark series for testing performance; each has its own features and advantages. However, do the performance results verified by the software really meet the requirements of the actual machine?
Based on the SNIA Test Standard, ADATA has developed a set of test software for the Linux environment; on the basis of the test projects and test conditions that the application platform requires, it can verify whether the SSD application model meets the requirements of the actual machine. The software can execute the SNIA Solid State Storage (SSS) Performance Test Specification (PTS) v2.0 test.
The ADATA SSS PTS TEST is currently an open source software with a source code that is available to all SSD vendors or relevant partners to download and install. Please refer to this website:https://github.com/Alan-ADATA/SSS-PTS-TEST.
SSS PTS Introduction
As regulated by the SNIA Solid State Storage (SSS) Performance Test Specification (PTS) v2.0 test, the importance of the SSS PTS test method for SSD performance evaluation can be easily illustrated through the following figure:
*Source: Solid State Storage (SSS) Performance Test Specification (PTS) Version 2.0.1
According to the figure, a brand new SSD usually experiences a short period of high performance before transitioning to a steady state. The steady state is usually used as the base for the performance indicator to evaluate the product under normal operation.
As explained above, through the test projects that are covered in the SSS PTS test tool, each performance indicator of the solid state drive (SSD) can be verified. The actual test image of ADATA SSS PTS on the screen is as shown below:
