Difference between Big-O and Little-O Notation
...rue if you used little-o:
x² ∈ O(x²)
x² ∈ O(x² + x)
x² ∈ O(200 * x²)
The following are true for little-o:
x² ∈ o(x³)
x² ∈ o(x!)
ln(x) ∈ o(x)
Note that if f ∈ o(g), this implies f ∈ O(g). e.g. x² ∈ o(x³) so it is also true that x² ∈ O(x³), (again, think of ...

Storing SHA1 hash values in MySQL
...racters. But if you use 8 bit per character, you would only need a 160/8 = 20 character long field.
So I recommend you to use BINARY(20) and the UNHEX function to convert the SHA1 value to binary.
I compared storage requirements for BINARY(20) and CHAR(40).
