I don't fully understand why you buy a new computer with such a small disk that it isn't even big enough for your current needs, let alone your future needs. How small is it? And how full already?
That being said, just buy a second hard disk (big enough this time) and put it inside the case. Don't use an external for iTunes. Don't use an external for storing anything. Just for backup. So if you have two (small or big?) disks inside your new computer, you might need even a very big disk (up to 4 TB) for backup. And one backup is not enough. So your next visit to the shop: 1 internal disk for your data, 2 external disks for backup.

To conserve disc space on my Brand new computer, I have been thinking of purchasing a separate hard drive to store my itunes and photos.
Is this possible, or can I run itunes just using the separate hard drive.
Could someone please advice this computer novice (I am 70 years old).
