KIOXIA introduces industry's first PCIe 4.0 OCP "NVMe cloud specification"-enabled SSD

New KIOXIA XD6 series E1.S data center NVMe SSD optimized for hyperscale, open compute project applications

  • Düsseldorf, Germany, 6 November 2020

KIOXIA Europe GmbH, the world leader in memory solutions, expanded its broad portfolio of client, enterprise and data center SSDs with the addition of the KIOXIA XD6 series E1.S form factor SSDs. KIOXIA's XD6 series are the first[1] E1.S SSDs to address the specific requirements of hyperscale applications, including the performance, power and thermal requirements of the Open Compute Project (OCP)[2] "NVMe Cloud SSD Specification." KIOXIA's XD6 drives are now sampling to select data center customers.[3]

Designed to maximize system density, efficiency and simplicity, KIOXIA's EDSFF E1.x SSDs represent the future of flash storage for servers in cloud and hyperscale data centers. Leveraging the OCP "NVMe Cloud SSD Specification," the flexible, efficient, small form factor E1.S replaces the bare module M.2 form factor and delivers greater density, and better performance, reliability and thermal management. E1.S is also designed to be hot-pluggable for increased serviceability, which is another benefit over M.2.

"The XD6 EDSFF E1.S is our next-generation form factor, which will power future generations of SSDs optimized for data center server platforms. KIOXIA is proud to work with local industry leaders on developing innovative storage solutions using our XD6 series," said Paul Rowan, Vice President SSD Marketing & Engineering, KIOXIA Europe GmbH.

PCIe 4.0 and NVMe 1.3c specification-compliant, KIOXIA's XD6 series is available in E1.S 9.5mm, 15mm and 25mm form factors. The XD6 series were designed for consistent performance, low latency and reliability in 24/7 cloud data centers.

Key features include:

  • Sequential read and write performance up to 6,500MB/s and 2,400MB/s respectively
  • 15W power consumption
  • Security options: TCG Opal[4]
  • Full end-to-end data path protection
  • Power loss protection
  • Expanded drive health information
  • Consistent performance and low latency against data center loads
  • New in-house developed, hyperscale-optimized controller

KIOXIA is an active and contributing member to the industry development of EDSFF E1.S/L and E3.S/L solutions, and continues to collaborate with leading server and storage system developers to unlock the full power of flash memory, NVMe and PCIe.
