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

TOKYO--(BUSINESS WIRE)--Nov. 09, 2021

Kioxia Corporation today announced the industry’s first lineup of Enterprise and Datacenter Standard Form Factor (EDSFF) E3.S SSDs designed with PCIe® 5.0 technology[1] – the KIOXIA CD7 E3.S Series, bringing in a new era for flash memory used in servers and storage. Building on Kioxia’s E3.S development samples that received a ‘Best in Show’ award at last year’s Flash Memory Summit, the CD7 E3.S Series increases flash storage density per drive for optimized power efficiency and rack consolidation[2].

Breaking free from 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 address 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 allows EDSFF to deliver the performance promised by PCIe 5.0 technology and beyond.

Kioxia is an active and contributing member to the industry development of EDSFF solutions, and is collaborating with leading server and storage system developers to unlock the full power of flash memory, NVMe™ and PCIe.

CD7 E3.S Series Key Features

  • EDSFF E3.S form factor with capacities up to 7.68TB
  • Designed to the latest PCIe 5.0 specification and optimized for x2 PCIe lane performance
  • Using fewer PCIe lanes increases number of PCIe devices that can be supported
  • Built on Kioxia’s BiCS FLASH™ 3D TLC flash memory
  • Up to 6,450 MB/s read throughput and 1,050K random read IOPS
  • 75μs read and 14μs write latencies, which are approximately 17% and 60% lower latencies than Kioxia’s previous generation PCIe 4.0 SSDs, respectively.
  • LEDs are embedded on the case of E3.S models and the status of the SSDs can be recognized visually. This means that there is no need to implement additional LEDs, which traditionally were embedded in the drive tray of the system chassis, contributing to saving system cost.

The KIOXIA CD7 E3.S Series is now sampling to select OEM customers.

* Definition of capacity: Kioxia defines a megabyte (MB) as 1,000,000 bytes, a gigabyte (GB) as 1,000,000,000 bytes and a 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 1GB = 230 = 1,073,741,824 bytes and therefore shows less storage capacity. Available storage capacity (including examples of various media files) will vary based on file size, formatting, settings, software and operating system, such as Microsoft Operating System and/or pre-installed software applications, or media content. Actual formatted capacity may vary.
