KIOXIA Announces XD6 E1.S – Industry’s 1st PCIe 4.0 OCP NVMe Cloud Specification-Enabled SSD

KIOXIA is announcing their newest significant technological development for cloud data center applications. The new XD6 Series further expands KIOXIA’s broad portfolio of client, date center and enterprise SSDs. The E1.S form factor XD6 SSDs are the first Enterprise and Datacenter SSD Form Factor (EDSFF) SSDs that target the specific requirements of hyperscale applications, and include the power, performance and thermal requirements of the Open Compute Platform (OCP) NVMe Cloud SSD Specification.

KIOXIA’s EDSFF E1.x SSDs are designed to maximize system density, simplicity and efficiency, and as such represent the future of flash storage for cloud and hyperscale datacenter servers. The EDSFF consortium definition leverages the OCP NVMe Cloud SSD Specification to create a flexible and efficient small form factor E1.S, which replaces the M.2 form factor. E1.S delivers greater density, performance, reliability and thermal management, as well as being hot-pluggable for superior serviceability.

blankKIOXIA’s new XD6 Series is compliant with both the PCIe 4.0 and NVMe 1.3c specifications, and will be available in E1.S 9.5mm, 15mm and 25mm form factors. The XD6 Series is designed for consistent performance, latency and reliability for 24×7 cloud data centers, and provides performance increases of 2x to 4x as compared to PCIe 3.0 SSDs. Key features are as follows:

  • Sequential read and write performance up to 6500MB/s, and 2400MB/s, respectively

  • 15W power consumption

  • Security options: non-SED and TGC-Opal

  • Full end-to-end data path protection

  • Power loss protection

  • Expanded drive health information

  • Excellent Quality of Service

  • New KIOXIA-developed, hyperscale-optimized controller
