It is all hidden in the documentation:

SetSize[^]

Establishes the size of an empty or existing array; allocates memory if necessary.

SetAtGrow[^]

Sets the array element at the specified index.
Remarks
The array grows automatically if necessary (that is, the upper bound is adjusted to accommodate the new element).
