14 DAY TRIAL // After some time of research and development, it seems that the JEDEC Solid State Technology Association has completed its two standards for solid state drives, which define conditions of use and corresponding endurance verification requirements.
The two standards that JEDEC has completed are JESD218 SSD Requirements and Endurance Test Method, and JESD219 Solid-State Drive Endurance Workloads.
SSDs are subject to different levels of demand depending on the application they are used in, so the standard defines two classes of such products.
According to JESD218, the two classes are Enterprise and Client, while the standard is also useful for establishing the specific requirements for each.
There is also a SSD endurance rating, which determines the number of terabytes written by a host to the SSD.
This is accomplished through two approaches, direct verification and extrapolation that is, which test endurance and retention.
Mostly, the rating should allow users to more easily compare SSDs from different manufacturers and the standard.
"To achieve the goal of consensus-based industry standards for SSDs, JEDEC's JC-64.8 Subcommittee for Solid State Drives has taken the lead to provide meaningful, real-life, endurance and reliability metrics to better enable customers to select the right SSD for their expected applications and workloads," said Alvin Cox, Chairman JC-64.8 and Senior Engineer, Seagate Technology. He added,
"In developing these standards, JC-64.8 collaborated with numerous other industry groups and standards associations and coordinated SSD-related changes needed in other existing standards to meet industry needs," he added.
The JESD219 SSD Endurance Workloads testing method defines the workloads that SSDs can cope with, though only enterprise workloads are described for now (client workloads will be added in the near future).
"Standards play a critical role in technology adoption and proliferation, and we are glad to have participated in development of the JEDEC SSD standards,” said Scott Graham, Vice-Chairman JC-64.8 and Technology Strategy Manager, Micron Technology.
“The comprehensive approach taken to defining capacity, workload and endurance will go a long way towards enabling market confidence in SSDs," he went on to saying.
