What Is the
DLTtape System?
QUANTUM DLTtape HANDBOOK

2.1
In later chapters we will cover a great deal of technical information
about exactly how DLTtape system technology works. In this chapter
we focus on what it is about the DLTtape and Super DLTtape sys-
tems that makes them unique. When you examine the details, there
are dozens of differences between the DLTtape system and other
tape systems. In this chapter we stick to the major points. Some are
obvious, and some are invisible, buried inside the product.
Speed, Capacity, Reliability
From a performance point of view, the characteristics that distin-
guish the DLTtape system from other tape storage technologies are
speed, capacity, and reliability. When compared to other technolo-
gies (see Chapter 11 for a detailed analysis), current DLTtape and
Super DLTtape drives offer very fast transfer rates (11MB/s native),
DLTtape cartridges store large amounts of data (110GB on a single
Super DLTtape I cartridge), and DLTtape drives can run longer,
under more demanding duty cycles, than any competitive tech-
nologies. Or, as one DLTtape sytem user put it, “You take the specs
for the 8mm solutions we used previously and multiply by about
4x, and that gives you the DLTtape technology spec.”
