Kioxia has shown the first benchmarks of next-generation solid-state drives that deliver double the bandwidth of existing models. The increase is provided by the transition from PCIe Gen 4.0 to PCIe Gen 5.0.
The PCIe Gen 5.0 SSD prototype delivers sequential read speeds of up to 14,000 MB / s and writes speeds of up to 7,000 MB / s. This is 103% and 67% more than the Kioxia SSD with PCIe Gen 4.0 interface. The random access speed is also almost double the speed, and the performance, measured as the number of I / O operations per unit of time, has increased by 50%. Finally, the read latency is 77% and the write latency is 50% of the corresponding Kioxia SSD with PCIe Gen 4.0 interface.
Kioxia plans to release its first PCI Gen 5.0 SSDs in the fourth quarter of 2021. These will be server models of the CD7 series, made in the EDSFF E3.S standard size and equipped with a PCIe Gen 5.0 x4 interface. Their capacity will be in the range of 1.6-30 TB, and the resource will be 1-3 DWPD. In the consumer segment, SSDs with a new interface will appear later, around 2022.
