Method and system for increasing data storage reliability and efficiency via compression

摘要

A method and a system is provided for increasing reliability of data stored in storage segments by increasing redundancy data and by permitting user data to fit around defective locations in the storage segment. User data is compressed and reserved for a portion of a storage segment having a data size corresponding to an uncompressed size of the user data. The compressed user data is written to the reserved portion of the storage segment and a pad byte pattern is written to any remaining portion of the reserved portion of the storage segment. The remaining portion of the reserved portion of the storage segment is designated as unused.
