I can't be the only one who needs more than 1 terabyte in a laptop, but doesn't want to pay Apple's obscene storage prices.

Now that Macbook Pros have SD card slots again, a solution presents itself: you can double a 1TB MBP' storage with a micro-SD card and a flush-mount adapter ($140 + $25) for less than half the cost of the same upgrade from Apple ($400).

It's obviously not as fast as internal storage, and you can't use that slot for anything else while the card is installed, but those are both acceptable trade-offs to me.

2TB is enough for me now, but if my needs grow in the future, I can swap out the micro-SD for the next few sizes that become available.

Or not? Because the SDXC standard supports cards from 64GB to 2TB, which only goes one size up from that, beyond which any SD card would be of the newer SDUC standard.

A lot of equipment from before the SDHC to SDXC transition didn't work with cards larger than 32GB. I remember finding that out the hard way with my Samsung Galaxy S. But I believe I've used 64GB cards in my 2009 Macbook Pro before, and a Panasonic camera from 2007? Apple's support document even says that SDXC cards work in any Mac with an SD card slot, though they may need to be reformatted before using. They also don't work in Bootcamp unless the Mac is from 2011 or later (this being the year after the first 64GB SD card was sold).

Can you see any such limitations affecting SDUC cards in the current Macbook Pros? Or is it worth buying one with the expectation that it will be able to read and write a 4TB SD card (or 8TB, etc) when such a thing comes onto the market?
 
For bulk storage the SD-card is cheaper, but if you want a card that is even 1/10th the speed of the internal SSD you will almost certainly pay more than what Apple is charging.

I went with 2TB internal and am thinking I’ll add a huge card for bulk-storage(e.g. for regular disk backups)
