Seagate’s 1TB hard drive will be our second generation 3.5-inch hard drive to feature capacity-boosting perpendicular recording technology, and it will use fewer heads and discs than similar-capacity products we expect to see from our competitors. It is clear that fewer heads and discs, along with our proven perpendicular technology, can increase drive reliability, and also reduce operating temperatures, power consumption, noise, and weight.
Seagate did not give a definitive release date for the product, but said it would be sometime before the second half of 2007. It will be accomplished using four platters instead of three, so it should definitely have some weight to it.
