Oh okay but how will you do the mounting of the drives since it's hard to figure out where the mount points should be :-) > The reason I keep saying 2GB is because that seems to be the current > "sweet spot" where the price per gigabyte is lowest, and the > performanc is at least "good".

I guess that would explain it why the Seagate Elite's were so popular :-) Vince GaiaNet Corporation - Unix Networking Operations - GUS Mailing Lists Admin
