Samsung, here are the new ZNS SSDs for data centers

Samsung

Samsung unveiled its first solid state drives Zones Namespaces (ZNS) which combine high performance, long life, relatively low price (thanks to the use of V-NAND QLC) and improved Quality Of Service (QoS) for data centers .

ZNS SSDs work differently than conventional block-based drives and have numerous advantages. ZNS SSDs sequentially write data in large zones and offer better control over write, reducing over-provisioning requirements. For example, some enterprise drives rated for 3 DWPD (drive writes per day) reserve around one third of their capacity for over-provisioning, but only 10% is sufficient for ZNS SSDs.

Also, Because ZNS uses large zones rather than many four-KB blocks, garbage collection is not required as often as traditional SSDs, while also improving real-world read and write performance. Samsung's ZNS PM1731a 2.5 ”SSDs are based on a proprietary dual-port controller and 6th generation V-NAND QLC memory. The drives will be available in 2 and 4 TB capacities. Samsung claims its new ZNS PM1731a drives will last up to four times longer than conventional NVMe SSDs, which will reduce Total Cost Of Ownership (TCO) and simplify server infrastructure.

However, the improved durability and performance come at a cost. The ZNS ecosystem requires a new software infrastructure that is not yet widely available. In an effort to make ZNS more popular, Samsung is participating in a number of open source ZNS projects. The manufacturer also plans to make its ZNS technology available to xNVMe and participate in the Storage Performance Development Kit (SPDK) community to allow NVMe and SPDK users to implement ZNS more easily.

Samsung will start mass production of its ZNS PM1731a SSDs in the second half of the year. Sangyeun Cho, senior vice president of the Memory Software Development Team at Samsung Electronics, said:

Samsung's ZNS SSD reflects our commitment to introducing differentiated storage solutions that can substantially improve reliability and the lifespan of server SSDs. We plan to leverage quad-level cell (QLC) NAND technology in our next generation ZNS drives to enable greater performance and storage capacity in tomorrow's business systems.
