Code sample:

=================================================
import std.stdio;

union Anonymous {
        char[9] buffer;
        align(1) struct {
                align(1):
                        int a;
                        int b;
                        char c;
        }
}

union Named {
        char[9] buffer;
        align(1) struct Name {
                align(1):
                        int a;
                        int b;
                        char c;
        }
}
void main() {
        writeln(Named.sizeof);
        writeln(Anonymous.sizeof);
}

=================================================

Output:

An unnamed struct/union allocates storage for its members. A named one does not, it just defines a type. Hence the size difference.
