Abstract:
1. A storage system comprising: a non-volatile semiconductor memory; a drive interface configured to receive host data sectors from a host interface; a buffer managing module configured to store the host data sectors in a buffer; a compression module configured to compress the host data sectors to generate compressed host data sectors, wherein lengths of the compressed host data sectors are different; a generating module configured to add nuisance data to the compressed host data sectors to generate drive data sectors, wherein the nuisance data comprises (i) all zeros, (ii) all ones, (iii) null states, or (iv) redundant data, and wherein the nuisance data is added to the host data sectors such that the drive data sectors are of a same predetermined length; and a control module configured to store the drive data sectors in the non-volatile semiconductor memory.
