KIOXIA’s PCIe 4.0 Enterprise NVMe SSDs Take Storage Performance to New Heights

Groundbreaking CM6 Series Achieves PCI-SIG Compliance and NVMe Certification; On Display at Supercomputing 2019

SAN JOSE, Calif., November 13, 2019 – KIOXIA America, Inc. (formerly Toshiba Memory America, Inc.), the U.S.-based subsidiary of KIOXIA Corporation, today announced that its lineup of PCIe® 4.0 NVMe™ enterprise solid state drives (SSDs) has achieved PCI-SIG® compliance for PCIe 4.0 and University of New Hampshire InterOperability Laboratory (UNH-IOL) certification. KIOXIA’s CM6 Series successfully passed interoperability tests at the August 2019 PCI-SIG Compliance Workshop – the first workshop to include official PCIe 4.0 specification tests. KIOXIA America will be on hand at Supercomputing 2019 later this month to showcase new levels of flash performance enabled by its CM6 Series SSDs. Demonstrations with nCorium and EchoStreams running a parallel file system workload can be seen at EchoStreams’ booth #1490 on the show floor of the Colorado Convention Center.

The first company to publicly demonstrate PCIe 4.0 SSDs, KIOXIA has established itself as a leader in developing PCIe 4.0 NVM Express™ SSDs and continues to push the limits of flash storage performance. The CM6 Series brings planned performance improvements of 3x over its PCIe 3.0 predecessors and is 12x faster than SATA drives1. KIOXIA’s lineup of Gen4 PCIe SSDs also includes the CD6 Series, which is targeted to cloud and scale-out environments.

Key Features:

  • Utilizes KIOXIA’s 96-layer BiCS FLASH™ 3D flash memory
  • PCIe 2x2 or 1x4 lane configuration options
  • Targeted transfer rates up to 6,900 megabytes per second1
  • Supports SFF-TA-1001 (also known as U.3) operation with Universal Backplanes for simplified customer use with SAS, SATA and NVMe SSDs

KIOXIA was at Microsoft Ignite earlier this month to demonstrate the CM6 Series running in a Microsoft Azure hyperconverged infrastructure (HCI) platform with Quanta Cloud Technologies – and enabling 2x performance gains over a PCIe 3.0 solution. “We were able to show that our CM6 Series SSDs are capable of pushing SSD sequential read performance to over 55 gigabytes per second (GB/s) across eight drives – nearly 7GB/s per SSD – and we’re not done yet. KIOXIA will continue to push the performance envelope for our customers,” noted Alvaro Toledo, vice president of SSD marketing and product planning for KIOXIA America, Inc.

PCI-SIG hosts Compliance Workshops several times a year in various locations worldwide, giving members the opportunity to test and validate their products before entering the field. Compliance testing is completed against both PCI-SIG maintained systems and other leading manufacturers of PCI products. As the leading testing and certification lab for NVMe technology and software, the UNH-IOL provides conformance and interoperability testing across various operating systems, drivers, and hardware platforms, as well as PCIe SSDs and PCIe-enabled servers. “The SSD market is quickly moving to NVM Express technology, and standards compliance is critical to ensure smooth adoption,” added Toledo.
