Abstract:
A method for low power storage array with metadata access includes sequentially writing data to a currently active disk drive in a storage array and storing metadata relating to the writes in a preallocated portion of the currently active disk drive, determining when the currently active disk drive is nearing full capacity, activating a next disk drive and cloning the stored metadata from the preallocated portion of the currently active disk drive to a preallocated portion of the next disk drive. When the currently active disk drive is full, sequentially writing data to the next disk drive.
