The Sony SDX-250V drive uses data compression to achieve high capacity and high transfer rates. Actual capacity and transfer rate depends on the source file type.
The capacity ratings listed in the next subsection are based on a 98 meter tape AIT-E Turbo cassette. The Sony SDX-250V drive is a high capacity data storage device using Advanced intelligent tape (AIT) technology. The Sony SDX-250V drive achieves high data integrity through read-after-write, an additional level of Error Correction Code, and other features.
