Efficient Data Transfer to/from Storage Medium of Computing Device

An application issues an application command to a file system of the computing device, where the application command includes a location of data at a source. The file system allocates space on a medium for the data and compiles a list including an identification of each portion of the medium that is to be used to store the data. The file system then issues a file system command to a block driver of the medium, where the file system command includes the location of the data at the source and the compiled list. The block driver contacts the source, requests the data at the location thereof, and writes the data to the portions of the medium included in the compiled list.
