Cons of having hash table big enough to reduce chances of collision:

1. Lot os space (memory)is used up.
2. if there aren't enough items in the hash, then the space allocated gets wasted.

apart from the above mentioned reasons,
if there is data skew, then increasing space does not help in avoiding collisions.

The reason a hash table is accessible in O(1) time is that it's stored in a contiguous block of memory, where each hash value corresponds to a specific memory address. Thus, the more spaces available in a hash table, the more memory it takes up.
