While Western Digital and Seagate chose to offer 2 TB HD spinning at 5,400 RPM, Samsung decided too use also 500 GB/disc, but to offer 1 TB models spinning at 7200 rpm. While having a smaller storage space, performance levels of those drives could be 30% higher than previous models. In addition, Samsung will also offer cheaper 1 TB drives as they will only 2/3 of the discs and heads usually required for such storage space.
