See full text

A hierarchal storage management method is provided. The method includes detecting a first portion of a first file being deleted from a hybrid storage device including a hard disk drive (HDD) memory device, a solid state drive (SSD) memory device, and an archival storage memory device. A first set of memory blocks associated with the first portion of the first file is identified. The first set of memory blocks are determined to reside on the SSD memory device. In response, the first set of memory blocks are transferred from the SSD memory device to a first portion of the hybrid storage device.
