Green IT is often equated with poor performance because high efficiency is usually only possible with limited power. The HDD specialist, Seagate, proves with the BarraCuda that the opposite is now possible. Although hard drives aren\'t typically the power guzzlers in a PC, the fact that the Seagate Barracuda is an economical model is clear. It is therefore rather surprising that the HDD, despite a significantly lower power consumption percentage, enables a rich data transfer of 190 megabytes per second. The BarraCuda achieves this dream value with a speed of 5,400rpm. Nevertheless, it remains restrained in terms of volume development and offers a lot of storage space with 8TB.The BarraCuda is very economical, quiet and at the same time enormously fast, when compared with the many HDDs of other manufacturers.
