Solid state disk with hot-swappable components

A solid state disk (SSD) device includes a non-volatile storage module (NVSM), a secondary power source coupled to power inputs of the SSD, a volatile memory (VM), a controller in communication with the NVSM and the VM. The controller is operable in a (re)populate mode to (re)populate data stored in...

Summary:A solid state disk (SSD) device includes a non-volatile storage module (NVSM), a secondary power source coupled to power inputs of the SSD, a volatile memory (VM), a controller in communication with the NVSM and the VM. The controller is operable in a (re)populate mode to (re)populate data stored in the NVSM to the VM when primary power is initially applied to power inputs of the SSD and further operable in a primary power on mode to replicate data to the NVSM that was written to the VM in response to received I/O requests while primary power is applied to the power inputs of the SSD. The secondary power source can be decoupled from the power inputs of the SSD while the controller is operating in either the (re)populate mode or the primary power on mode.
