If you do such a replacement the drive size will be "clipped". That means if you have 5x36 GB drive, remove one, and put in a 140 GB drive, only 36 GB out of it will be used. I'm pretty sure this will also happen if you try to extend the array by adding bigger drives to the already existing array. The only way is to tear the array down and re-define it with bigger drives.
