Awhile back I picked up a Microsoft Surface 3 tablet from Amazon. (Not the wide-aspect Surface Pro.) On-board storage is (I think) a nominal 150 GB. I'm unlikely to use that all up doing what I have in mind, but the Surface does have a microSD card slot, so I'd like to toss a card in there and use that for data files to preserve the on-board space for programs (or "apps," as Windows 10 insists on calling them).
If I'm going to do it, I think I'll just go for a 128 GB card so I only do it once. I found on Amazon a Samsung EVO and a SanDisk Ultra, both priced withon about 50 cents of each other. Which one should I choose?
