Kioxia recently released the industry’s first PCIe 5.0 solid-state hard drive CD7, which is specially designed for data centers and servers, adopts EDSFF E3.S specifications, and has a maximum capacity of 7.68TB.
Kioxia’s US official website that Kioxia stated that the CD7 solid-state drive is based on last year’s E3.S full-featured development platform, which increases the flash memory density of each hard drive and optimizes the overall power efficiency.

This solid-state drive breaks through the 2.5-inch form factor design limit and is specially optimized for high-performance, high-efficiency servers, and storage requirements.
Moreover, Kioxia CD7 SSD uses Kioxia’s own BiCS FLASH 3D TLC particles, is designed with PCIe 5.0 specification, supports x4 PCIe lanes, but is also optimized for PCIe Gen5 x 2 performance, making its performance similar to PCIe Gen 4 x 4, which greatly saves the occupation of PCIe channels.
In terms of performance, the CD7 SSD has a read throughput of 6450 MB/s, random read 1050K IOPS, a read latency of 75μs, and a write latency of 14μs, which are 17% and 60% lower than the previous generation PCIe 4.0 SSDs.
