Micron and Astera Labs joined forces at DesignCon 2025 to demonstrate the world’s first PCIe 6.0 SSDs using the Astera Scorpio PCIe 6.0 network switching device. Combined with two Micron PCIe 6.0 SSDs and an Nvidia H100 GPU, the device achieved sequential read speeds of more than 27GB/s on each drive — twice the speed of the fastest PCIe 5.0 drives today.
Micron’s new PCIe 6.0 SSD was first unveiled at the Astera Labs booth at DesignCon 2025 in late February. Official test results were published last week on the Astera Labs blog.
Micron has confirmed that the SSD is the same device that was announced last August as the industry’s first PCIe 6.0 drive. At the time, its claimed read speed was 26GB/s, but the Astera Labs test bench bumped it up to 27.14GB/s.
For comparison, the fastest PCIe 5.0 SSD on the market today, the Crucial T705, delivers a maximum read speed of 14.5GB/s, which is half as fast as Micron’s new SSD.
These record-breaking speeds are made possible by the Astera Scorpio P-Series Fabric Switch, the industry’s first PCIe 6.0 network switch to support up to 64 PCIe 6.0 lines.
Designed to enable fast communication between CPU, GPU, and storage in high-performance computing clusters and AI systems, this switch uses Nvidia Magnum IO GPUDirect (GDS) software. This software enables storage to directly access GPU memory, bypassing the CPU buffer and reducing latency for even greater performance.
