Assumes a 2:1 compression ratio. Actual compressed capacity varies depending on the type of data being
recorded. The VXA-320 tape drive uses the ALDC (Adaptive Lossless Data Compression) algorithm and
integrated circuit chip. The ALDC algorithm is compliant with the European Computer Manufacturers
Association (ECMA) standard. Data compression is controlled by the software application. Enabling or
disabling the tape drive’s hardware compression is controlled by the backup application.
