A file delivery system includes a disk file system, a solid state drive file system, and an interface module. The disk file system includes a disk drive that stores a plurality of files for download by a user device. The solid state drive file system includes a solid state drive that stores a first block of data for each of the files stored on the disk drive. The interface module is in communication with the disk file system and with the solid state drive file system, and is configured to retrieve the first block of data of one of the files from the solid state drive in response to a request from the user device for one of the files, to send a read command to the disk drive for a next block of the one of the files at substantially the same time as the first block is retrieved from the solid state drive and sent to the user device, and to store the next block in a buffer.
