At geek homes world-wide, there has been a feud about whether or not Solid State Disks (SSD) are or are not more power efficient than normal hard disks. Because, next to faster throughput speeds, that was the whole selling point. IN fact, early SSDs were not very power lean, but many thought this was merely a quick design.
Then Tom's Hardware, good ol' German Nerd Tom, did a big test and published figures that showed that SSDs were in fact also power hungry. War started... Now, Engadget reports Tom's Hardware redid the test, paying close attention to details this time and found that indeed SSDs are - in most cases - more power efficient than regular hard disks! Pfffew! Let the dust settle
BTW, this is the clear winner (by far)
