RE: Re: 1TB "Green" Drives

As a matter of interest, I just completed a rebuild of one of my 24x7
servers with a specific intention of reducing its energy usage.

I measured it before I started at 200W in steady state, - it fluctuated a
little of course, say +-10W either side, but 200W was pretty much the
average.

I've replaced virtually every component as follows:

Gigabye GA8I45P Pro   --->   Asus P5Q-WS
Pentium 4 3.0GHz        --->   Core 2 Duo 2.13GHz
5 x WD 400GB SATA (RAID edition)    ---->  5 x 1TB WD (Green edition)
2 x Maxtor 250GB 3.5" IDE  --->   2 x Samsung 120GB 2.5" SATA
nVidia 6600 PCE-Ex16 (with fan)   ---> nVidia 7300GT with passive
cooling

PSU is the same, memory is the same, cooling is the same.  Vista's
performance index is the same

Using the same meter, I measured this last night at a more-or-less constant
110W, - that's a pretty good improvement! I'm using the Asus EPU power
management feature of the new mobo, and set the level at "medium power
saving"

I'm also going to stop running this box 24x7, as having thought about how I
use it, I realised that having it on all day during the week when no-one's
home was just pointless. So using a combination of the BIOS wake-up
feature, and a Windows scheduled event, I'm havint start up at 17:30 every
day, and shut down at 01:30 each morning. running it for just 8 hours/day
rather than 24 will obviously cut its energy use by 2/3rds as well, which
is no bad thing...

Thanks, but still seems like a fair few watts.

Yes, that's the way I might go. But the atom pulls just a few watts and
the current chipsets a few 10s of watts. I guess the chipsets need to
catch up.
