i have a 40gb hdd currently that's pretty much packed, so for christmas my sister is planning on buying me another 40gb (so i can put them in Raid 0). But it has come up that someone else would like to chip in for this gift, thus there is more money to spend and they'll probably get me a 60gb hdd. But the problem is: how the heck will i fill up 100gb? i only have about 17gb of music and about 8gb of movies. and i have more movies on cds.
so my question is: is it worth asking them to spend the extra money to get a 60gb? or should i just stick with 40
