JEDEC launches SSD standards

An industry group has released new standards for measuring the endurance and reliability of solid-state storage devices, which it claims will make it easier to compare devices from different manufacturers.

The new standards come from the JEDEC Solid State Technology Association, and comprise the JESD218 SSD Requirements and Endurance Test Methods and JESD219 Solid-State Drive Endurance Workloads.

The idea behind both documents is to provide a standardised means of testing the endurance and reliability of solid-state storage devices, which will make it far easier to compare the relative merits of devices from differing manufacturers.

Alvin Cox, senior engineer at storage specialist Seagate Technology and chairman of the JEDEC subcommittee that developed the standards, said that the group 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."

As well as an SSD Endurance Rating, which represents the number of terabytes written to an SSD before it falls over, JEDEC's metrics specify a pair of Application Classes - Client and Enterprise. Using a rigid set of measurements, it's possible to determine whether the SSD you're about to put in your datacentre is genuinely suited to enterprise-grade use.

Micron Technology's technology strategy manager Scott Graham, who was also involved in the production of the standards as the subcommittee's vice-chairman, added that "the comprehensive approach taken to defining capacity, workload and endurance [in the standards] will go a long way towards enabling market confidence in SSDs."

Both standards documents are available for free download now, but it remains to be seen if manufacturers choose to implement them in their testing procedures.
