aThe VXA-320 (VXA-3) tape drive does not support VXAtape V6, V10, or V17.
bMaximum capacity is obtained using VXA-320 (VXA-3) format; assumes the host computer keeps the tape drive streaming.
cOne gigabyte equals 1,000,000,000 bytes.
dAssumes 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.
