According to WD, the new hard drives, Caviar Green, “consume up to 20 percent less power and offer a 10 percent increase in performance over the previous version.” Skeptical? You’ve been well trained. What exactly lets these drives draw so much less juice? Western Digital cites three factors. First, there’s IntelliPower, which balances spin speed, transfer rate, and caching algorithms for efficiency, not raw speed. Then there’s IntelliSeek, again a focus on optimum seek speeds to lower power consumption. And finally, the NoTouch ramp load technology, which ensures the recording head never touches the disk media, meaning spin-up from standby state is faster and takes less energy.
