Kioxia Introduces Industry’s First EDSFF SSDs Designed With PCIe® 5.0 Technology

New KIOXIA CD7 E3.S Series EDSFF E3.S Data Center SSDs Optimized for Density and Efficiency

TOKYO, November 09, 2021– (BUSINESS WIRE) – Kioxia Corporation today announced the first line of E3.S Enterprise and Data Center SSDs (EDSFF) designed with PCIe® 5.0 technology[1] – the KIOXIA CD7 E3.S series, opening a new era for flash memory used in servers and storage. Building on Kioxia’s E3.S development examples 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 to 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 provides improved airflow and thermals, and signal integrity benefits. 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.

Kioxia is an active member and contributor to the industrial development of EDSFF solutions, and works with leading developers of servers and storage systems to unleash the full power of flash memory, NVMe â„¢ and PCIe.

Main features of CD7 E3.S series

  • EDSFF E3.S form factor with capacities up to 7.68TB

  • Designed to the latest PCIe 5.0 specification 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

  • Read latencies of 75 and 14 write, which are approximately 17% and 60% lower, respectively, than Kioxia’s previous generation PCIe 4.0 SSDs.

  • LEDs are integrated into the housing of the E3.S models and the status of the SSDs can be recognized visually. This means there is no need to implement additional LEDs, which were traditionally built into the system chassis drive tray, helping to lower system costs.

The KIOXIA CD7 E3.S series is now sampled for some OEM customers.

* Capacity definition: Kioxia 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 = 230 = 1,073,741,824 bytes and therefore displays less storage capacity. Available storage capacity (including examples of various media files) will vary depending on file size, formatting, settings, software, and operating system, such as Microsoft operating system and / or preinstalled software applications, or multimedia content. Actual formatted capacity may vary.
