Industry Standard
DDS-4
The DDS-4 technology has a drum rotation speed of 8,503 rpm while the tape moves at 11.6 mm/s. Features of the
format allow a linear bit density greater than DDS-3, which increases transfer rate and capacity.
Investment Protection
The 20/40-GB DAT autoloader uses a compatibility mode to read and write DDS-1, DDS-2, DDS-3 and DDS-4 tapes.
This offers investment protection for users who have standardized with the DAT technology. Users will also have
the ability to restore archived media from previous backups and interchange with previously shipping DDS-3 6 and 8
cassette Autoloader drives.
Lowers TCO with
Automation
Automated DAT backup systems offer lower total cost of ownership with a higher storage capacity and
performance than a stand alone tape backup drive and is targeted at the price sensitive environments.
