Samsung unveiled ZNS SSD with enhanced lifespan  for next-gen enterprise servers

On June 2nd, Samsung launched its new enterprise SSD (solid-state drive) that features Zoned Namespace (ZNS) technology i.e. the PM1731a. By using ZNS tech, the SSD will maximize available user capacity and deliver an extended lifespan in the storage servers, cloud environments, and data centers.

ZNS, which is a next-generation technology, can divide the entire storage space of an SSD into small-capacity areas, and store data in the same area with a specific purpose and use cycle through efficiently using SSDs. ZNS SSDs can significantly reduce the number of write operations even without moving or rearranging stored data.

It reduces the SSDs write amplification factor (WAF), which is the number of actual writes performed by the drive compared to writes initially instructed by the host system. The closer the WAF is to one, the more efficient the SSD and the longer it will last.

The new 2.5-inch PM1731a, which is built on Samsung’s 6th generation V-NAND, will available in two terabytes (TB) and four TB models. At the same time, it also features dual ports, which means the other optimized port can be used to run the storage server stably if an error occurs on one of the ports during use.

It’s official: Samsung plans to mass-produce ZNS SSDs in the second half of the year and continues to work with global enterprise storage companies to optimize their ZNS drives in various customer environments.
