Overview
The Quantum LTO-4 (Model B) Half-Height Tape Drive is a high-performance
16-channel tape drive that complies with the LTO interchange specifications.
The drive is suited for mid-range to high-end servers, mainframe systems,
and tape library automation systems.
The LTO-4 (Model B) Half-Height Tape Drive uses Ultrium data cartridges. Its
capacity is maximized using intelligent data compression. The drive has a
native capacity of 800 Gbytes (1,600 Gbytes assuming 2:1 data
compression).
The LTO-4 (Model B) Half-Height Tape Drive has a 5¼-inch half-height form
factor with automatic electromechanical cartridge soft load. It is available in
two models:
