Kioxia has showcased the first performance benchmarks of its next-generation PCIe 5.0 based SSD solutions which will offer twice the bandwidth compared to existing Gen 4.0 solutions.

Being the world's 2nd largest manufacturer of flash memory products, Kioxia has stated during an event that it will be launching its first PCI Gen 5.0 SSDs as early as Q4 2021. The SSDs will be known as the CD7 series and will come in 2.5" EDSFF E3S form factor initially with a Gen 5.0 x4 connection before moving to a standardized NVMe platform. The drives will also be aimed at the data center 8-channel controller and enterprise 16-channel controller segments first before arriving in consumer segments.
