Barracuda hard drives from Seagate give you with the Power of One. One
terabyte per disc technology. One drive platform for every capacity need and
every desktop storage application. One hard drive qualification effort. One hard
drive platform to choose from. One hard drive with trusted performance,
reliability, and simplicity to deliver the lowest total cost of ownership.
You no longer need to choose between low power drives, mainstream drives, or
performance drives. One hard drive with 7200RPM performance and capacity points
from 250GB to 3TB makes it easier than ever to choose the right drive for any
need.
You get more bang for your buck with 1TB per disc technology. Increasing the
capacity per disc means the highest capacity drives like 1TB, 2TB and 3TB become
more affordable, needing fewer discs to meet your capacity needs.
From desktop or all-in-one PCs, to home servers, to PC-based gaming systems
and more, Seagate Barracuda drives are ideal for nearly any application. They
work great in desktop RAID configurations, as well as in direct-attached
external storage devices (DAS) and network-attached storage devices (NAS).
