If we have a lot of space it's must be very good and don't need to upgrade much.In the future if we need more space but we have a small hard drives only 40-60GB so we don't suitable for application or document.But if we want to save digital media like songs ,images or video.I suggest you to buy hard drives at least 80GB.

A better way for upgrade space for your laptop is increase external hard drive which set up with
USB port or firewire port.
