"The major feature of Seagate’s new Barracuda 7200.10 hard drive is the use of perpendicular recording technology that boosts the capacity of the drive by an impressive percentage. Perpendicular technology stands the particles of magnetic media on their end instead of laying them on their side. The result is a significant increase in areal density so we’ve leapt from the 500GB of the Barracuda 7200.9 to an enormous 750GB from the Barracuda 7200.10 family. In other respects the 7200.10 is a conventional SATA300 hard drive, with a 7,200rpm spin speed and support for NCQ (Native Command Queuing) so we’re going to dwell on the areal density and 750GB capacity throughout this review."With so many of the technology announcements I read, it takes years for them to come to market - and quite often then never make it. When perpendicular storage breakthroughs were announced, I was excited but also skeptical - what if we didn't see this until 2012? Well, my skepticism was misplaced, because the leap came, and we have a massive 750 GB hard drive to show for it.
