Micron and Astera Labs achieve 27GB/s SSD speeds through PCIe 6.0

Forget PCIe 5.0 – Micron and Astera Labs are hitting record speeds with PCIe 6.0

At DesignCon 2025, Micron and Astera Labs have delivered a public demonstration of their PCIe 6.0 technologies. This demo highlighted the interoperability of Micon’s PCIe 6 enterprise SSDs, and Astera Labs’ Scorpio P-series Fabric Switch. Using this setup, the team achieved 27GB/s sequential read speeds.

This demo showcased SSD speeds that are two times faster than the fastest PCIe 5.0 SSDs. This demo has revealed the performance that will be available in the PCIe 6.0 era, when PCIe 5.0’s bandwidth will no longer be a limiting factor.

Consumer-grade PCs have little use for PCIe 6.0 connectivity right now, but enterprise and AI workloads can benefit from this faster interconnect. It can enable faster data transfers, lower latency communications, and more scalable system architectures.

Now that we have seen public demos of PCIe 6 compatible hardware, it is only a matter of time before the rest of the hardware ecosystem catches up. Consumer-grade SSDs like the Samsung’s 9100 PRO already push the limits of the PCIe 5.0 interface. How long will it be before new server and consumer-grade CPUs support PCIe 6?
