I understand that the current X-PHY® AI Embedded Cyber Secure SSD solution is M.2 2280, is it possible to scale down the SSD size to 2260 or 2240?

No, X-PHY® AI Embedded Cyber Secure SSD is designed to a M.2 connector PCIe Gen3x4 interface standard and NVMe 1.3 protocol. However, Flexxon has future plans to release a U.2 Drive compliant version in X-PHY® AI Embedded Cyber Secure SSD Solution product roadmap .
