I don't think there's any ideal value for a max allocation size, I can't even think of an use for such large arrays. There is always a way to split the allocation in smaller ones which will be easy to map in the available virtual memory space. If its a single stream, loading it all in memory at once is overkill, it would be more efficient to create a specialized range to load something like 0x1000 bytes at once (aligned to the same boundary) and operate on this slice.
