KIOXIA showed the first tests of SSD with PCIe 5.0 interface a few months ago. The company has now announced the industry’s first line of CD7 SSDs in the Enterprise and Data Center (EDSFF) E3.S form factor, designed with PCIe 5.0 technology.
Free from the design constraints of the 2.5-inch form factor, the EDSFF E3.S form factor drives, the company says, are tailored for the needs of high-performance, high-performance servers and storage systems. This form factor enables next-generation SSDs to be used for future datacenter architectures while supporting many new devices and use cases. It offers improved air circulation and thermal performance, and improves signal integrity. E3.S drives support a higher power budget than 2.5 ”drives and better signal integrity, allowing EDSFF devices to deliver the performance expected of PCIe 5.0 and future releases.
The drives use KIOXIA’s 3D TLC BiCS flash memory and come in capacities up to 7.68TB. Claimed sequential read speeds up to 6,450 MB / s and up to 1,050,000 random read IOPS. The read and write latencies are 75 μs and 14 μs, respectively, which is about 17% and 60% lower than the previous generation KIOXIA PCIe 4.0 SSDs. The E3.S has built-in LEDs so that status can be visually determined, eliminating the need to install additional LEDs traditionally built into the media tray, thereby reducing system costs.
KIOXIA is currently shipping samples of its CD7 E3.S series drives to selected OEMs.
