Abstract: Methods, systems, and computer program products are provided for deduplicating data mapping a plurality of file blocks of selected data to a plurality of logical blocks, deduplicating the plurality of logical blocks to thereby associate each logical block with a corresponding physical block of a plurality of physical blocks located on a physical memory device, two or more of the corresponding physical blocks being non-contiguous with each other, determining whether one or more of the corresponding physical blocks are one or more frequently accessed physical blocks being accessed at a frequency above a threshold frequency and being referred to by a common set of applications, and relocating data stored at the one or more frequently accessed physical blocks to different ones of the plurality of physical blocks, the different ones of the plurality of physical blocks being physically contiguous.
