If you are just runnig iTunes, you would be wasting your money to upgrade IMO.
But what if OP will change his/her mind and one days he/she want's to use it more "heavy"?
I already have a 5TB external SSD HD. I'm wondering if 1.4 is big enough to do the job or should I step up?I have that exact machine (the 2014 1.4GHz). It was dog slow until I attached an external USB SSD, which is boots and runs from. Now it's a super server for AppleTV and Time Machine for my Macs. I bought Samsung's 500GB T5 SSD from Amazon. It's $160, but you can get a 250GB one for $125.
I have a new MBP I use for the heavy computer work but when I take the computer with me for school and work but that leaves the rest of my household unable to access my library and the 5TB worth of stuff.Yes, I agree. You are absolutely right.
But what if OP will change his/her mind and one days he/she want's to use it more "heavy"?
You know: browsing the web, watching "bigger resolution" videos etc.?
The web of the future will be more and more demanding every year and will need even more raw performance.
Of course he/she can sell this computer and buy something else.
Because this Mac mini is not really upgradeable. Well, except for the HDD.
And I made a point that I WILL only be using it as an iTunes Library computer. There was no typo on my part. Thanks to all!Well in that case he shouldn't have made a special point of saying it was SOLELY for iTunes.
I agree, the base 4gb mini is a very limited machine and does not offer much promise for the future. But it's more than adequate for running iTunes, and it can be left on an old software version if iTunes or MacOS have greater future requirements (mine is still running El Capitan - just don't see any reason to bother with updating).
