    PSD same res but huge file size difference

      Hi everyone, I have this puzzling question I like to find an answer to.

       

      I have 2 PSDs of the same size and dpi but their file size are hugely different (188kb vs 30mb). Why is this so?

       

      The file description are as follow:


      :: Image A (188kb) ::

      2.6cm x 2.6cm, 300dpi, greyscale, 8bit, Transparent background. Only one layer, unflattern.
      Image on the layer is a thin circle line with a "X" inside. No smart object or vector inside this PSD.

       

      :: Image B (30mb) ::

      2.6cm x 2.6cm, 300dpi, greyscale, 8bit, Transparent background. Only one layer, unflattern.

      Image on the layer is a thin circle line with a "Y" inside. No smart object or vector inside this PSD.

       

      To summarize both are circle logo on a transparent layer, unflattern. I have no idea why their file size are so different. Can someone explain?

       

      Thank you
