KIOXIA Introduces Industry’s First EDSFF SSDs Designed With PCIe 5.0 Technology | Business


SAN JOSE, Calif .– (BUSINESS WIRE) – November 8, 2021–

A new era for flash memory used in servers and storage has arrived, and it is introduced by KIOXIA America, Inc. Today, the company announced the first line of E3.S SSDs for enterprise and data center ( EDSFF) designed with PCIe ® Technology 5.0 1 – the CD7 series. Building on the KIOXIA E3.S full development vehicle that received the “Best in Show” award at last year’s Flash Memory Summit, the CD7 E3.S series increases flash storage density per drive for a optimized energy efficiency and rack consolidation 2.

Overcoming the design limitations of the 2.5-inch form factor, the EDSFF E3 family is optimized for the needs of high-performance, highly efficient servers and storage. EDSFF enables the next generation of SSDs to accommodate future data center architectures, while supporting a variety of new devices and applications. It offers improved airflow and thermals, signal integrity benefits, and options for larger SSD capacity points. EDSFF standardizes the status LEDs on the drive, eliminating the need for LEDs on the drive carriers. Support for higher E3.S power budgets than 2.5-inch form-factor SSDs and better signal integrity allow EDSFF to deliver the performance promised by PCIe 5.0 technology and beyond.

Based on KIOXIA’s innovative fourth-generation BiCS FLASH â„¢ 3D flash memory technology, the CD7 series supports PCIe x4 lanes, but is optimized for PCIe Gen5x2 performance, which is similar to PCIe Gen4x4 performance, saving two PCIe lanes valuable for additional peripheral connections. KIOXIA is an active member and contributing to the industrial development of EDSFF solutions, and collaborates with leading developers of servers and storage systems to unleash the full power of flash memory, NVMe ® and PCIe technologies.

“The EDSFF E3 form factor is designed to redefine the way enterprise servers and storage are designed,” noted Greg Wong, Founder and Senior Analyst, Forward Insights. “We expect the market to switch to EDSFF from 2022, with the introduction of systems based on PCIe 5.0. “

Main features of the CD7 series

  • EDSFF E3.S form factor with capacities up to 7.68TB 3
  • Designed to the latest PCIe 5.0 specifications and optimized for PCIe x2 lane performance
  • Using fewer PCIe lanes increases the number of PCIe devices that can be supported
  • Built on KIOXIA BiCS FLASH â„¢ 3D TLC flash memory
  • Up to 6450MB / s read throughput and 1,050,000 random read IOPS
  • 75s read and 14s write latencies, respectively 17% and 60% lower than previous generation PCIe 4.0 SSDs.

“We see EDSFF as the enterprise NVMe SSD form factor of the future,” said Neville Ichhaporia, vice president, SSD marketing and product management, KIOXIA America, Inc. “The E3 versions, optimized for the next generation of enterprise platforms, are well suited to keep pace with technology with the incremental demands that data-intensive applications place on servers and storage. This will help customers optimize the performance, cooling and storage capacity of next-generation servers and storage. “

More information on EDSFF E3 technology can be found in this white paper from Dell, HPE, and KIOXIA. The KIOXIA CD7 series is now sampled to select OEM customers. For more information, please visit

1: As of October 25, 2021, based on an industry survey of publicly available information

2: Compared to 2.5 inch form factor SSDs.

3: Capacity definition: KIOXIA Corporation defines megabyte (MB) as 1,000,000 bytes, gigabyte (GB) as 1,000,000,000 bytes, and terabyte (TB) as 1,000,000,000,000 bytes. A computer operating system, however, reports storage capacity using powers of 2 for the definition of 1 GB = 2 ^ 30 bits = 1,073,741,824 bits, 1 GB = 2 ^ 30 bytes = 1,073,741,824 bytes and 1TB = 2 ^ 40 bytes = 1,099,511,627,776 bytes and therefore shows less storage capacity. Available storage capacity (including examples of various media files) will vary depending on file size, formatting, settings, software and operating system and / or preinstalled software applications or media content. Actual formatted capacity may vary.
