That's not the desired behaviour actually, what I want is to gain the
maximum space without the possibility of loosing data, I hear that ZFS
is excellent at recovering data so I'm trying to figure out the
perfect installation with these drives and of course while keeping the
data safe... RAID0 is good for not wasting space at all but then again
if one drive fails I'll lose everything :(

What do you think guys? Should I do something or it's better just to
leave them the way they are ( every drive has it's own, currently ext3,
FS ) ??
