Solid State Drives Two Standard Specifications Announced

Although the development of SSDs has entered a period of high tide, the performance, reliability, and other indicators of different manufacturers are individualized and it is difficult to make horizontal comparisons. To this end, the United States Electronic Devices Engineering Joint Committee (JEDEC) finally announced today the highly anticipated SSD standard specification, which can be downloaded for free.

The first is the SSD Requirements and Endurance Test Method numbered JESD218, which defines the usage of SSDs and the corresponding durability verification requirements, and is classified into customers and companies depending on the application area. (Enterprise) Two major categories, each of which has defined detailed requirements specifications, can help ordinary consumers and IT managers better choose the SSD products that suit them.

JESD218 also has a solid-state drive durability rating that represents the amount of TBW written by the host controller to the SSD. This provides a standard comparison method of SSDs based on the usage level. Users can easily compare the differences. Manufacturer's SSD product.

This is followed by the SSD Endurance Workloads numbered JESD219, which is a complementary standard. Because SSD workloads have a huge impact on the amount of data they can write (ie, their lifetime), standardized workloads are necessary to achieve comparable results. JESD219 currently only defines enterprise-class SSD workload standards, and consumer-grade ones will be added in the near future.

In particular, Alvin Cox, chairman of the JEDEC JC-64.8 SSD subcommittee, is the senior engineer of Seagate, the largest mechanical hard disk drive manufacturer.
