Does Gen6x4 Make Sense for SSDs Claiming 25W Due to Standard Form Factor Recommendations


Should SSDs supporting power states higher than the maximum TDP dissipation supportable in a system? Many industry standards for drive form factors are targeting <=25W, but will Gen6 SSDs be viable in a x4 configuration or will these form factors be abandoned? What is proposed is a framework currently supported in NVMe and OCP's Datacenter NVMe SSD Specification of allowing enhanced latencies in cases where there is thermal margin above the maximum TDP of the form factor using either host orchestrated NVMe power state management or device orchestrated Host Controlled Thermal Management. The topic will also explore some enhanced terminology around thermal and electrical power limits to help facilitate the discussion.
