HPE Discover: SK Hynix Unveils Low-Power NVMe eSSD With 72-layer TLC 3D NAND

SK Hynix Inc. announced that it launched a low-power NVMe enterprise SSD (eSSD) with the 72-layer TLC 3D NAND flash that offers performance for power as well as QoS.

The product features an in-house NVMe controller on top of the 72-layer 3D NAND technology currently in mass production.

With the launch, the company has established itself as a memory producer that designs, develops, and mass-produces all key components, from NAND and DRAM to controllers, in-house, for client but also enterprise applications.

Meanwhile, power consumption of datacenters is an increasingly important in terms of energy and environmental preservation, as their footprint grows amid rising enterprise demand for cloud, AI, and ML. As datacenters are expected to account for one-fifth of the world’s energy consumption in 2025, low-power components that enable datacenter energy efficiency are expected to grow.

This NVMe SSD targets the mainstream eSSD market with performance, power and cost. With an 8-channel NAND interface, the drive provides the maximum density of up to 4TB in the M.2 form factor and 8TB in U.2., and delivers sequential read of up to 3.2GB/s and random write of 160,000 IO/s at 14W or below.

Compared to the eSSD with 72-layer 256Gb 3D NAND, announced at the August 2018 Flash Memory Summit and qualified with major datacenter companies, this SSD improves sequential read by 30% and random write by up to 70% at the equal capacity and form factor. It supports both read-intensive and mixed-use applications, such as internet data centers, AI, ML, or VDI.

With this product, the firm seeks to secure a leading edge in the eSSD market as it transitions from SATA to NVMe. These SSD began its qualification with cloud service providers and server makers, with volume production slated to begin in the second half of 2019. The company also plans to launch a 16TB eSSD based on 96-layer 4D NAND at the end of this year, with mass production starting next year.

“Not only cloud hyperscalers, who already adopt NVMe as the mainstream interface, but also traditional datacenters are planning to make the transition. I hope SK hynix will excel in the eSSD market, thanks to the best-in-class performance of its NVMe offering,” said VP Kim Samil, VP, head, NAND storage marketing, SK hynix.

According to market researcher Forward Insights, NVMe SSDs are expected to make up more than half of the enterprise SSD market in 2019, with the NVMe interface accounting for 90% or more of total SSD gigabytes by 2023.

To promote the product, the company displayed it at marketing events such as HPE Discover in Las Vegas, NV.
