158856-002 Compaq DDS4 20-40GB Internal SCSI DAT Drive

Description

The 158856-002 is the Compaq branded Sony DDS4 internal SCSI DAT drive.

The DDS / DAT (Digital Data Storage / Digital Audio Tape) format was initially developed by a collaboration between Sony, HP and Digital in 1991 and uses helical scanning for recording, the same process used by a video cassette recorder (VCR). If errors are present, the write heads rewrite the data.

DDS DAT tapes used between Sony DDS1 and the DDS4 have a width of 3.81mm, known as 4mm, to give a compressed capacity of up to 40GB.

The Sony SDT-11000 half height tape drive is the fourth generation in the DDS family and the second DDS4 drive that Sony Produced. It was manufactured by Sony for vendors including Compaq and Dell, for use as standalone internal and external drives targetting the small business market.

The DDS4 offers 20GB native capacity or 40GB compressed capacity on a single tape at transfer speeds of up to 4720KBps or 16.9GB per hour. Native, the drive provides 20GB of storage capacity with a transfer speed of 2360KBps

The SDT-11000 drive employs the same technology as previous DAT products, and uses DDS4
media in order to achieve higher capacities. However, it maintains backward compatibility and can still read and write data to DDS4, DDS3, DDS2 and DDS1 4mm tapes.

The SDT-11000 was only available in 68pin Wide Ultra LVD/SE SCSI, interface versions.
