A storage block may include a first portion allocated for storage of network data associated with a storage network. The storage network may include the storage block and one or more other storage blocks. The storage block may further include a second portion allocated for storage of local data. The local data may be associated with one or more programs of a device that includes the storage block. Additionally, the storage block may include a third portion as free space of the storage block. The third portion may be maintained at approximately a target size through adjustments made to an amount of network data stored on the first portion.
