Naomi you make a good point. I have just purchased my first digital camcorder and am finding that the video clips are quickly using the remaining space on my 40 G HD which was about half used before the camera’s debut. I have a 160 G external HD to back things up. I got that hardware recently and got it big in anticipation of the camera and upgrades to follow and actually, in part, because of discussion here when I asked about back up options a while back.
I have learned a lot from this discussion here and am thinking that at this point I may just try to keep adding to my current box as long as the motherboard can support it and it makes sense.
