Backblaze designed and built their own servers that are specialized for their business model. Everything except the case is commodity. http://blog.backblaze.com/2011/07/20/petabytes-on-a-budget-v2-0revealing-more-secrets/ Allows them to offer a service with a price point that would not be anywhere near possible with AWS or other enterprisy solutions. Of course enterprisy solutions would not have you (would not give you the option of) asking your friends and family to mail you hard drives, so you can stay in business: http://blog.backblaze.com/2012/10/09/backblaze_drive_farming/ (No financial interest. I am a customer, Backblaze fits well in my multi-tiered backup strategy.)

Congratulations. Enjoy Rock Hard Awesome and The Lady Babies. I only took four weeks off when my twins were born. Six months would be pretty awesome.
