Samsung ZNS SSD features

Samsung Electronics unveiled its new solid-state drive featuring Zoned Namespace (ZNS) technology—the PM1731a. According to Samsung, ZNS allows data to be grouped based on their usage and access frequency and stored sequentially in independent zones within an SSD. In addition, the ZNS SSDs can 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. “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. The ZNS will also allow users to take advantage of the SSD's full capacity by eliminating the need for overprovisioning, which requires storage space for background tasks. Samsung plans to mass-produce its ZNS SSDs in the second half of the year and continue working with global enterprise storage companies to optimize its ZNS drives further.
