What is smaller when saving to SQL database?

when saving blank column sql database, of these 2 options uses least amount of space on hard drive?

null or ""

would there benefit using 1 on other?

might silly question when databases large think can make difference.

thanks not laughing hard.

ideally, should using null

"" value - though not contain value still value

where null undefined , has no value.

i not have excat metrics storage wise null better data type

if of data in column null, can make column sparse--it have better savings in storage
