SD card (256GB overkill?) for Spin 13 Chromebook (revised question)

newtochromebook

Hello, I got a great tip this morning to buy a Sandisk 128GB SD card for my used Spin 13 I just ordered off EBay, and almost certainly will purchase it. Nevertheless, I’m reposting a question about SD that I attempted to post here last night but accidentally did non the wrong (non-Chromebook Spin laptops); I’m reposting here because I’m curious if other parts of the question elicit any helpful ideas or tips, and if anybody has experience with 256GB (overkill?) SDXC cards. So the following is recycled from last night:

Hello, just ordered a used Spin 13 from Ebay, never even used a Chromebook at all before. Went this route after my old PC laptop (Windows) and Samsung Note Pro 12.2 died the same day, leaving me with no computer devices except my phone. Mostly I only do the basics: word processing, surfing the web, reading the news online, streaming movies (mostly TCM; I'm a dinosaur); but with one exception: a research project involving scanning and reading thousands of pages of documents. I opted for the Spin 13 mainly for the screen and that as a convertible I can read music off it on the piano (perfect aspect ration for that, as well as reading documents and writing).

Based strictly on the above (and so far unmentioned severe financial plight, extremely limited $ resources), if I were going to invest another $15-25 (may $40, max) in an SD card to give the biggest boost (right now focused on the thpusands of scanned pages I want at my fingertips, even offline), and dozens of Kindle books too (forgot to mention above), what SD will give me most bang for my buck, hopefully bringing this to the level of the Acer 713 128GB I really wanted, or even beyond that?

Obviously I'm fairly unsophisticated about computers, kniw nothing about SD cards, never used one. Do they make a 64GB computer the same as a 128GB one just by adding a 64GB card? In what ways yes, what ways no? Will it fit entirely inside the device without sticking out? Again, any answers, super super super super appreciated, should be based strictly on what I've written above. If you had to rank purchases (on ebay, not necessarily retail price), what will give biggest bang for my buck, value for money? Will spend on the higher end of 15-40, but only if the gains in power and performance far far better than $25 in other words. Every dollar counts in my situation, but no problem with $40 if it makes my machine monster-powerful. 

Thank you so, so, so (x 500) much more any feedback; under a lot of stress over replacing my original computer, nervous about transitioning to Chromebook and what I may be giving up. Anything to make this a truly positive step, super, super appreciated. Thank you so very much again, for **any** helpful information and tips!

Oops... “accidentally posted on the wrong forum” (non-Chromebook); again, thanks so much for **any** feedback! (Incl. any tips about how to get the most out of my Chromebook; as my comment suggests, I’m accustomed to Windows laptops and bought the Spin Chromebook because it’s the most affordable convertible 2-in-1 laptop-tablet with 2K definition and 3:2 (or is it 4:3?) aspect ratio, extremely important to me... given my uses, Chromebook should be fine for me, but obviously I’ve been skeptical about Chromebook... so again, and tips/feedback super-appreciated!)
