High Performance byte[] to Hex String Converter

HexUtils.cs

public static class HexUtils
{
  private const string HexAlphabet = "0123456789abcdef";

  public static string ToHexString(byte[] bytes)
  {
    return string.Create(bytes.Length * 2, bytes, (chars, buffer) =>
    {
      var charIndex = 0;
      var bufferIndex = 0;
      while (charIndex < chars.Length)
      {
        var b = buffer[bufferIndex];
        chars[charIndex] = HexAlphabet[b / 16];
        chars[charIndex + 1] = HexAlphabet[b % 16];
        bufferIndex++;
        charIndex += 2;
      }
    });
  }
}

When run against the same profiler this is measurably faster than even the fastest algorithm included in this stack overflow answer, and considerably faster than the the accepted answer.
