Notebook battery source life boosts due to flash disks?

Notebooks have a necessity in more battery source life. My choice was a notebook with flash disks for the most part of 90s and its 10-hour source was quite appropriate for me. You possess a greater portability when there is no necessity in charging notebook battery source within a certain period. I had a great interest in the ability of flash disks to expand the laptop battery source life. Applying a kilowatt energy meter I processed some experiments on Intel Core 2 Duo laptop. Energy consumption is more sophisticated that I'd considered. This is the facts I discovered. Notebook configuration:

MacBook with Core 2 Duo for 2 GHz,
2 GB RAM,
Intel 950 integrated graphical unit,
13-inch display
8x DVD Burner
160 GB Western Digital Scorpio 2.5" 5400 RPM hard drive,
Bluetooth,
Wi-FI

The prettiest thing about this laptop is that the disk burner is simple to remove (it can be watch through a 1 minute video). I processed the experiments with a built-in Scorpio disk turned out and turned the MacBook on with assistance of an externally supplied FireWire drive. Instruments applied: Additionally to the kilowatt energy meter that is located between the wall power supply and the MacBook energy adapter, I also applied the best open source application called MenyMeters. MM indicates CPU, disk, network and memory usage, commonly set through a user-chosen 1-2 second time frames.

The experiments: I loaded the operating system in course of shooting the energy usage with both the built-in and external drives. I also turned on a disk defragmentation utility, reputable iDefrag to provide perfect disk I/O. As the system was turned on, I tested some of various subsystems, as well. Screen power usage was experimented with the screen turned off and at minimal and ultimate brightness. Optical burner power usage was tested by playing a DVD and burning a CD. Idle energy usage with the display turned off and CPU at a 3-4 percent level was tested as well. I also pulled out a 1 GB SO-Dimm. The effects: The fact is that to investigate energy supply you should just shut down properties and turn them on. For instance, operating I/O is an action needing central processing unit supply both over Wi-Fi or to drive. When the defragmentation process was on it needed from 80 to 95 percent from both of dual units, for an eight watt action - practically 3x of an occupied drive.
