An original version of content is in-place updated to an updated version in a non-volatile storage device including blocks, by obtaining an update package, copying the original version to volatile memory, and updating the original version to provide an uncompressed updated version. The methods may also include compressing the uncompressed updated version so as to independently or interdependently compress each amount of uncompressed updated content and writing the compressed updated version in place of the original version in the storage device. Each of the independently compressed amounts may be written to a separate storage blocks.
