Solid State/Magnetic/Optical Storage
Host Interfaces
Allow the device to be attached to the processor. Important considerations are bandwidth and command overhead.
Storage Device Interfaces
Provide a standard protocol for communicating with the host interface adapters.
Native Device Interfaces
Low level interface with commands mapping directly to device functions
High Level Interfaces
Embedded controller translates the native device interface to a higher level protocol such as USB or Ethernet allowing easier integration with Host device drivers.
