Seagate Barracuda 1TB HDDs

摘要

Seagate has added two new 1 TB drives to its Barracuda fleet of HDDs, namely the Barracuda 7200.11 and ES.2. These use Perpendicular Magnetic Recording (PMR) technique on four platters, which results in higher data density than achieved with traditional Longitudinal Recording technology and hence high-storage capacity in small form factor, ie 250 GB per disk plate.
