A system and method for storage and continuous delivery of a plurality of data files in a data stream are disclosed. The system and method include storing at least one data file of the plurality of data files, allowing each user to select the at least one data file for delivery, and transferring data from the first disk and the second disk alternately over a bus to at least one user. The at least one data file includes a plurality of data blocks and is stored by storing the plurality of data blocks in a first disk and a second disk. The first and second disks further include a plurality of blocks. Storing the at least one data file further includes the steps of (a1) storing a data block of the plurality of data blocks in a next available block of the first disk, (a2) storing a next data block of the plurality of data blocks in a corresponding block on the second disk, and (a3) repeating steps (a1) and (a2) until the at least one data file is completely stored. The at least one data file is stored on a first plurality of adjacent blocks in the first disk and a second plurality of adjacent blocks on the second disk. The method includes performing a first seek operation to find a next block on the second disk while a read and data transfer is performed for a current block on first disk and performing a second seek operation on the first disk to find a next block on the first disk while a read and data transfer is performed for a current block on the second disk.

System and method for striping data across multiple disks for continuous

A method and system for storage and delivery of a plurality of data files is disclosed. The method and system include dividing at least one data file of the plurality of data files into a plurality of data blocks. The method and system further include storing the at least one data file by storing the plurality of data blocks in a plurality of disks, allowing a user to select any data file of the plurality of data files for delivery, and transferring the selected data file from the plurality of disks. Each disk includes a plurality of blocks having a disk block size. Storing the at least one data file includes storing a data block of the plurality of data blocks in a next available block of one disk, determining a complementary block on a next disk, storing a next data block in the complementary block on the next disk, and repeating the prior two steps for each of the plurality of disks until the at least one data file is stored. Transferring the selected data file further includes performing a seek operation on one disk to find a next block on the one disk while a read and data transfer is performed for a current block on another disk.
