Performance per Watt, Streaming Reads
Hitachi’s new Deskstar 7K1000.B drive is one of the most efficient drives when it comes to delivering sequential data streams, as it only requires 6.8 W while doing this. The WD Caviar Black requires 7.7 W for the same task. Let’s look at the performance per watt results.
The WD Caviar Black drive isn’t as fast as the Hitachi 7K1000.B in this benchmark, and it requires more power than Hitachi’s drive for this task.
