Originally introduced as a Digital Audio format (Digital Audio Tape), 4mm drives quickly came into use as a data storage medium using the DDS (Digital Data Storage) nomenclature.

The last new drive was in November 2009 when HP launched the DAT 320, which stores up to 160 GB uncompressed (marketed as 320 GB assuming 2:1 compression).

Avax can offer refurbished versions of the entire DDS range.

Note –  The Flash Card based Magnetic Tape Replacement is available as a ‘Plug & Play’ replacement for 4mm DAT drive
