You need to think about a few things.
i) Do you need to have everything (work, documents, media, etc) on your Macbook when ‘away from home’? Or just some essential working files?
ii) How are you going to gain access to a MyCloud when mobile? Are you going to use free WiFi hotspots, or a mobile data contract on a phone, or some other means?
iii) Do you hope to access your media on a MyCloud when ‘away from home’? Media gobbles data bandwidth, so if you’re using a mobile phone as a data service, you’ll need to think about the data contract.
iv) What do you use for playing music on the Macbook (assuming that’s what you use to play music)?
v) What internet access facilities will you have access to at university? Will you be in on-campus accommodation, or in private digs?
If you need to have everything with you, then a disk expansion for the Macbook seems likely.
If you don’t need to have everything with you, you could use a MyCloud as your primary or ‘master’ data store, and access it locally via your router, either wired or wireless. You could transfer older files to an ‘archive’ area on an external storage device, and probably not need to expand the Macbook.
You could use the new 1TB disk as an external backup device for the MyCloud (using the MyCloud’s ‘SafePoint’ automatic backup system), but, of course, you would run into problems when your 2TB MyCloud fills beyond 1TB… In theory, you could buy a second 1TB disk and connect both to the MyCloud via a USB hub, but I’m not sure how seamlessly the MyCloud will use these for SafePoint backups.
If you use a MyCloud as a primary store for an iTunes library, it is likely that iTunes will get confused if you try to use it away from home, since it will not be able to find its music library. iTunes will try to be ‘clever’, and move its library to its local disk, thinking it is being helpful. This causes people some trouble when they then return home and want to reconnect to the iTunes server on the MyCloud. I think there is a solution to this, but I don’t use a Mac or iTunes, so don’t have any experience of this, only what I’ve read here.
If you’re going to be in campus accommodation, you need to consider whether the bandwidth available through the university internet infrastructure will support remote media or document access, and whether it will be possible to make your MyCloud private (i.e. does each student have a private LAN, or do they all share access to a common LAN?)
I have a 4TB MyCloud I use as my primary data store, with about 2TB of media on it. I have very little data storage on my desktop PC (it has a tiny disk by modern standards), or on the Android tablets or Android media player I use. I access my 4TB drive in my local network (at home) to play music on PC or Android devices. This MyCloud not made available remotely. I back up this MyCloud using a manual method that is a modification of the process I have been using for years, by connecting USB drives to my PC, and running a backup script to copy data from MyCloud to USB disks. This is probably not a suitable solution for you, and the automated SafePoint might suit you better.
I have a second 2TB MyCloud that I have made available remotely, which holds my music collection compressed to MP3, and other documents and information I want to be available when I’m mobile. I don’t access my media remotely much (and only via tablets or media player), and don’t listen to a lot of music when I’m away from home. This is a ‘slave drive’ and I copy things to it from my 4TB ‘master drive’.
I’m going to guess that the Apple Store suggested you should sign up to Apple’s Cloud storage service…
