I replaced my 64 gig with a 1tb sabrent rocket. The speeds alone are worth it no matter what. Going to desktop and back is like magic. I always install from scratch though, more steps for less hiccups is the way I always look at it
I bought the 256 GB deck. That filled up fairly quickly obviously and I looked at the alternatives. It turns out that if you buy the right SD Cards they're basically the same speed as the SSD, so I just bought a 1TB Samsung EVO and it's been great. Also, I didn't have to lose the existing 256 Gb of space that I had and it was zero effort.
Maybe one day I'll upgrade to a 2TB internal, or maybe I won't.
Exactly what I did. I went for the 1tb though. The storage prices for the deck are pretty outrageous and upgrading is pretty easy. So a 64gb deck + 1tb card comes out to be about the same as a 256gb deck.
