Abstract: A method or system capable of providing additional storage capacity using small form-factor (“SFP”) non-volatile memory (“NVM”) solid state drive (“SSD”) with modular to modular configuration is disclosed. A system includes a processing device, SFP auxiliary plug (“SAP”), and power SAP. In one embodiment, the processing device includes multiple SFP sockets operable to provide data communication. The SAP, having a SSD connector and an auxiliary connector, facilitates storing information persistently via NVM. The SSD connector of SAP is used for communicating with the processing device when the SAP is plugged into one of the SFP sockets. The power SAP, having a power connector and a power extension connector, is capable of providing electrical power to the SAP when the power extension connector and the auxiliary connector are coupled or connected.
