In July 2012 the School of Podcasting had 25,000 downloads of all my back catalog. In looking at my episodes, they average around 20 M
25,000 X 20 M = 500,000 M
500,00 M = 500 G
Ignoring the amount I would get charge for uploading the four files in July, just the bandwidth alone would be $57.63
Throw on top of it that there are no stats, and I continue to say that while Amazon S3 may cheap when you start – it eventually costs you more than Libsyn.com or Blubrry.com (I use the Libsn.com $15 a month plan). You can get a free month at libsyn.com using the promo code sopfree.
