The published MTTF (Mean Time To Failure) for your basic LED is WAY beyond the MTTF of a DW1655. MTBF (Mean Time Between Failure) won't matter because once anything in this drive fails it will be cheaper to replace than repair. It does add to the LED pollution in your house. Seriously, with the number of LEDs and instant on appliances in the typical home, the 10mA here and there add up to several hundred watts of baseline power consumption. Wasteful Americans! (tic) I have two power settings on my PC: always on for DVD mastering and hibernate-after-10-minutes for when I'm not burning.
