The new KIOXIA XD8 series is the third generation of E1.S SSDs, is compliant with PCIe 5.0 (32GT/s x4) and NVMe 2.0 specifications, as well as support Open Compute Project (OCP) Datacenter NVMe SSD v2.5 specification. According to KIOXIA, the XD8 Series is based on an in-house controller, paired up with BiCS FLASH 3D flash memory. The KIOXIA XD8 series is designed for cloud and hyperscale environments, promising superior performance while maintaining operational efficiency.

The KIOXIA XD8 Series will be available in capacities of 1.92, 3.84, and 7.68TB, and offer sequential read and write performance of up to 12,500 MB/s and 5,800 MB/s, which is a 73 and 20 percent improvement, respectively. The random 4K read and write performance peaks at 2,300K and 250K IOP, a 48 and 25 percent improvement, respectively. As said, the KIOXIA XD8 Series comes in EDSFF E1.S form factor with 9.5 mm, 15 mm, and 25 mm heatsink options.

"The KIOXIA XD8 Series is engineered to deliver superior PCIe 5.0 performance over previous generation SSDs and optimize thermal management, addressing the needs of OCP hyperscale environments," noted Neville Ichhaporia, senior vice president and general manager of the SSD business unit at KIOXIA America, Inc. "As an active member of the OCP community, KIOXIA is committed to collaborating with leading server and storage system developers to harness the full potential of flash memory, NVMe, and PCIe technologies. Our continued innovation in this space ensures that the industry remains prepared to meet both current demands and future requirements."
