Seagate 6TB Barracuda 5400RPM 256MB Cache Internal Hard Drive - ST6000DM003Green 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 now the opposite. That this is an economical model, is clear. On the other hand, hard drives are not really the power guzzlers in the PC, so the real saving effect should not be overstated. It is therefore rather surprising that the HDD, despite a significantly lower power consumption percentage, allows a full data transfer of a respectable 185 megabytes per second. Even the fastest drives have problems with them. The BarraCuda achieves this dream value with a speed of 5,400 rpm. Nevertheless, she remains reserved about volume development. The BarraCuda is very economical, quiet and at the same time extremely fast, even in comparison with many HDDs from other manufacturers. So Green-IT not only convinces the mind, but also the heart.
