Even the crappiest of crap SD cards these days aren't that fragile. You'd
need to swap on the order of GB/s to wear it out that fast. Most of the SD
cards can handle hundreds of full drive writes. At 128GB, you're looking at
needing to generate about ~25TB of effective writes before you'd wear them
out. Even with a crazy 10x write amp (typical is 2-3), there's no way you'd
get that through an interface that's measured in the tens of MB/s.
