The second generation 4TB WD Black ushers in a new level of performance for consumer grade HDDs. This should allow gamers and creative professionals to achieve the performance and capacity they desire in one storage solution.
In our testing, the WD Black had no equals and if we look at the consumer HDD market at this point, you will see that it is the only offering available next to HGSTs 7K4000 with a 7200RPM spindle speed.
Now the obvious trade-off of the WD Black is power consumption, the drive used a touch over 10 watts in sequential workloads, and idle power consumption was not much lower at 8.3 watts. However, in my mind, if you are even thinking of using the WD Black, you are not concerned with power draw - you want performance and capacity.
As for use scenarios for the WD Black, I feel it would suit very well, consumers who want a high capacity, high performance OS drive for their gaming adding to this creative and media professionals that stream multiple large workloads.
