Thread: WD Caviar Green 1TB hard drive

Western Digital went Eco-friendly by launching a 1TB hard drive that's a miser when it comes to power consumption. As the capacity of a drive increases, the prower required to run such a drive also increases. but contrary to that, this Caviar Green 1 TB drive just sips on power when its power consumption is compared to the other two drives above.

It has a 32MB buffer memory which ensures accesses to the drive are reduced thus increasing performance. Caviar Green has a sub-7200 RPM spindle speed, unlike the other two. because it uses IntelliSeek technology that calculates optimum seek speeds to lower the power consumption as well as noise and vibrations.



This is the reason, at idle mode. it Consumes a meager 2. 8W of power while during read/write operation. it goes up to 5.4W which is nearly similar to Hitachi's power consumption of 5.2W in idle mode. The drive is quieter in operation and lower on power consumption. It can be used for secondary desktop storage or as a home file server. where performance can be traded up power saving.
