I don’t use Microsoft software at all. I’m not sure I know of any benefits of OneDrive over any other service given that?
I don’t know a lot about NAS, but one thing I do know is they’re not exactly cheap.
It depends. I just have a dual bay NAS with mirrored 4TB drives (so 2 x 4TB). That setup is about $370 on Amazon. Apple's upgrade to 4TB is $1,400.
One thousand and four hundred additional dollars on top of the price of the Macbook.
Add in an AC1750 router $75 (or AC1300 $30 will even do for the Air or low end 13") to the NAS price and it's still far cheaper.
To be honest, my first NAS failed (2TB mirrored) after 3 years, so my return is not as good as it cloud have been. I was hoping to get 6 years out of it, but the way I used my data has changed too and I'm now using more. So I replaced both the NAS
and the drives (although those drives are still in use today for non-NAS purposes); and that's not a good scenario financially. Let's say I get 5 years from my MacBook, so $1,400 over 5 years is $280/year. Let's assume I got 3 years from my first NAS, that's say $125/year for the first three years, and let's assume that in three years I am replacing my NAS again (some sort of catastrophe/upgrade again) then that's $125/year for the two years left. So 5 x $125 = $625. + router upgrade if needed, let's call it $75 if we have a higher end MacBook Pro, that's $700. That's really as bad as it could have been for me financially and it's still only half of the price of the 4TB MacBook Pro upgrade. I was hoping it was going to be perhaps a quarter. I can live with a half. The NAS economies actually get better as you go larger too, on a $/MB basis.
I didn't factor in resale at the end of life. I still have my old iMac that I need to get rid of. I don't plan on reselling this Macbook to fund a new one, but it's still worthy of consideration. I suspect the 4TB might command another couple of hundred over the 256GB if I sold it? I'm not really sure. So my horrible case scenario would be even worse, but a couple of hundred dollars on re-sale isn't material. I know there are plenty of ways to poke holes in the numbers and other people would use different valuation calculations.
It's not for everyone but it works well for me and is cheaper. NAS is also more than
just storage, though that's the primary reason to use it.
