title: Most efficient way to store and retrieve a 512-bit number?
body: <p>I have a String of 512 characters that contains only 0, 1. I'm trying to represent it into a data structure that can save the space. Is BitArray the most efficient way?</p>
  
  <p>I'm also thinking about using 16 int32 to store the number, which would then be 16 * 4 = 64 bytes.</p>
