Micron shows off world's fastest PCIe 6.0 SSD, hitting 27 GB/s speeds — Astera Labs PCIe 6.0 switch enables impressive sequential reads

Micron and Astera Labs teamed up at DesignCon 2025 to show off the world's first PCIe 6 SSDs in the wild, paired with Astera's Scorpio PCIe 6.0 network fabric switch. When connected to two Micron PCIe 6.0 SSDs and an Nvidia H100 GPU, the switch handled sequential SSD read speeds of over 27 GB/s on each drive — doubling the speeds of today's fastest PCIe 5.0 drives.

The new Micron SSD was first shown off at Astera Labs' booth at DesignCon 2025, a high-end chip design conference that took place in the last week of February in California. The companies waited to share info on the test bench publicly until this week on the Astera Labs blog.
