Samsung Electronics, the world leader in advanced memory technology, today unveiled its new enterprise solid-state drive (SSD) featuring Zoned Namespace (ZNS) technology — the PM1731a. Leveraging ZNS, the SSD will maximize available user capacity and offer an extended lifespan in storage server, data center and cloud environments.
“Samsung’s ZNS SSD reflects our commitment to introducing differentiated storage solutions that can substantially enhance the reliability and lifetime of server SSDs,” said Sangyeun Cho, senior vice president of the Memory Software Development Team at Samsung Electronics. “We plan to leverage quad-level cell (QLC) NAND technology in our next-generation ZNS drives to enable higher thresholds for storage performance and capacity in the enterprise systems of tomorrow.”
ZNS allows data to be grouped based on their usage and access frequency, and stored sequentially in independent zones within an SSD. Without the need to move and rearrange data, ZNS SSDs can significantly reduce the number of write operations, lowering the drive’s write amplification factor (WAF) — the amount 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.
