Astera Labs’ PCIe 6.x SSD demo reaches 27 GB/s, highlighting massive storage performance gains for AI and HPC data center workloads.
At DesignCon 2025, Astera Labs demonstrated PCIe 6.x interoperability, highlighting the significant potential of next-generation storage connectivity. Showcasing its Scorpio retimer technology, Astera Labs illustrated how the future of PCIe storage will evolve, tackling challenges like signal integrity at dramatically higher data rates.
Setting the Stage for PCIe 6.x Storage
PCIe 6.x represents a substantial leap forward from PCIe 5.0, effectively doubling available bandwidth per lane to 128 GT/s. In practical terms, this means that while Gen5 SSDs top out around 14,000MB/s, Gen6 SSDs will reach up to around 28,000MB/s. Improving
