Kioxia Introduces PCIe 5.0 NVMe EDSFF E1.S SSDs for Cloud and Hyperscale Environments

The second bullet of release dated October 15, 2024, should read: Sequential read performance up to 12,500 megabytes per second (a 73% improvement over the previous generation)⁽²⁾⁽⁴⁾ (instead of Sequential read performance up to 12,500 gigabytes per second (a 73% improvement over the previous generation)⁽²⁾⁽⁴⁾).

The updated release reads: 

KIOXIA INTRODUCES PCIE 5.0 NVME EDSFF E1.S SSDS FOR CLOUD AND HYPERSCALE ENVIRONMENTS

New KIOXIA XD8 Series Improves Performance, Offers Range of Capacities and Form Factor Options

Kioxia Corporation, a world leader in memory solutions, today announced the availability of its new KIOXIA XD8 Series PCIe^® 5.0 Enterprise and Datacenter Standard Form Factor (EDSFF) E1.S SSDs. The new drives are the third generation of E1.S SSDs from Kioxia and are compliant with PCIe 5.0 (32 GT/s x 4) and NVMe^TM 2.0 specifications, and support the Open Compute Project (OCP) Datacenter NVMe SSD v2.5 specification⁽¹⁾.

Designed for cloud and hyperscale environments, the KIOXIA XD8 Series meets the growing demand for higher performance, enhanced efficiency, and greater scalability in data centers. The new drives empower cloud providers and hyperscalers to optimize their infrastructure, delivering superior performance while maintaining operational efficiency.

Available in capacities of 1.92, 3.84 and 7.68 terabytes (TB), KIOXIA XD8 Series evaluation drives are now sampling to select customers.

Notes
(1) Not all requirements of the OCP Datacenter NVMe SSD v2.5 Specification are supported. Contact your Kioxia sales representative for more information.
(2) All performance improvements are comparisons to the previous generation KIOXIA XD7P Series SSD (7.68 TB capacity model). Specifications are subject to change without notice.

(3) IOPS: Input Output Per Second (Or the number of I/O operations per second)
(4) Read and write speed may vary depending on various factors such as host devices, software (drivers, OS etc.), and read/write conditions.

*Definition of capacity: Kioxia Corporation 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 = 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 based on file size, formatting, settings, software and operating system, and/or pre-installed software applications, or media content. Actual formatted capacity may vary.

*SED optional model supports TCG Opal SSC except for some features.
*SED optional model is not available in all countries due to the local regulations.

*NVMe and NVMe-MI are registered or unregistered trademarks of NVM Express, Inc. in the United States and other countries.
*PCIe is a registered trademark of PCI-SIG.
*The OCP and Open Compute Project marks are owned by and used with the permission of the Open Compute Project Foundation.
*Other company names, product names and service names may be trademarks of third-party companies.
