a
Maximum capacity: assumes the host computer keeps the drive streaming.
b
Assumes a 2:1 compression ratio. Actual compressed capacity varies depending on the
type of data being recorded. The 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.
c
One gigabyte equals 1,000,000,000 bytes.
