A storage device controller may segregate data units that are typically accessed together to a common storage unit. In one example, a storage device includes a control unit configured to receive a plurality of logical blocks to be stored in the storage device, wherein a first set of addresses comprises logical block addresses (LBAs) of the plurality of logical blocks, and a non-volatile memory configured to store logical blocks in a plurality of storage units, wherein one of the plurality of storage units includes logical blocks corresponding to a second set of addresses. The control unit may determine an intersection of the first set of addresses with the second set of addresses and to store each of the logical blocks having LBAs in the determined intersection of addresses in a common storage unit of the storage device, wherein the common storage unit comprises one of the plurality of storage units.
