/var/lib/postgres on Hitachi E5K160 60 GByte (Raid-1 + Hotfix)

Hello,

I am building a new small PostgreSQL Server for my Solar-Powered Mobil-
Office based on a Mini-ITX "VIA EPIA LN10000EAG" with 1 GByte of memory
where the OS (Debian GNU/Linux) is in three Hitachi TravelStar 20 GByte
(in a Raid-1 + Hotfix).

I am normaly working alone, but maybe the server would have connections
from up to 8 Workstations which are not realy heavy...

The controller is a 3Ware 3w8500S-8LP

And now it comes:

Does anyone has an experience on the special drives which can run 24/7
like the "Hitachi TravelStar E5K160 60 GByte"? I like to put three of
them into a Raid-1 + Hotfix.

The server is already running but /var/lib/postgres is currently on
three Western Digital Raptor WD740 which consuming over 45 Watt andare
laud liek an Combat-Aircraft... Three E5K160 would only consume arround
18 Watt.

Any Experiences?

Thanks, Greetings and nice Day
