Actually I've heard both, and the Inexpensive name seems to have come up LATER, probably some jerk off tech making fun of it, but that name stuck, even though I believe "Independant" is OLDER. Now I've heard people argue "they aren't independant if they are in an array". They are PHYSICALLY independant, meaning if you use a truely redundant array, the failure of one drive does not cause an array failure, becuase it's physically a different unit.
