family—delivers up to 1 TB of reliable digital storage.
Seagate has a proven record of delivering reliable products
in volume, and the new Barracuda 7200.11 family continues
the tradition. Designed with four platters that use the
highest areal density available in volume shipping
(250 GB/disk) along with second-generation Seagate PMR
technology, the Barracuda 7200.11 drive offers the ideal
combination of world-class technology and low total
cost of ownership. The reliability of this drive, along
with its 5-year limited warranty, ensures the longevity
and sustainability of digital content for years to come.

Highly leveraged from award-winning PMR technology,
the Barracuda 7200.11 drive increases capacity per disk
without increasing platter or head count. At the same
time, it enhances reliability by decreasing internal
components and increasing magnetic stability at high
areal densities.
