Performance of Arrays vs. Lists
...Array need to use:
So often as possible. It's fast and takes smallest RAM range for same amount information.
If you know exact count of cells needed
If data saved in array < 85000 b (85000/32 = 2656 elements for integer data)
If needed high Random Access speed
List need to use:
