Hitachi Releases World's Most Energy-Efficient HDD 118
An anonymous reader writes "Today Hitachi released what they are calling the 'world's most energy efficient desktop hard drive' capable of reducing the active and idle power consumption by up to 40 percent over the previous generation." The drive will come in a range of flavors starting at 250GB and ranging to 500GB. Hitachi is promising these drives in high volume later this year.

B) Latency. Nowhere did they mention the "wake-up" time from the Low RPM mode, but you can guarantee it's horrendous. "Average Latency" as the specs say, only tell you what happened during test conditions, conditions very unlikely to put it into Low RPM mode.
C) Density. Cutting edge drives are more dense.
If I were Google, these might sound like attractive trade offs.

Portable drives powered via the USB connection can take more power than USB permits. Get the drive well under that level and you wan't need to use those double-USB cables.
