C Hash Table - Advantages/Disadvantages of Binary files? -


i've been learning hash tables , binary files , wondering how viable method of data storage be. efficient read/write disk due added efficiency of binary files, or considered inefficient? i've heard term "hash disk" mentioned more once, not sure if active data management opposed reading dat file upon opening.

what advantages/disadvantages storing data in dat file rather in memory?
