An interesting little bit of calculation:

Apple iCloud: $0.99/month for 50 GB = $0.02/GB
Google Drive: $1.99/month for 100 GB = $0.02/GB
Box: $10/month for 100 GB = $0.1/GB
Office 365: $7.99/month for 1000 GB = $0.008/GB
Dropbox: $11.99/month for 2000 GB = $0.006/GB 

Sorted by smallest to largest firsts storage option. I’d include Amazon but having trouble pulling up prices on that.

I can’t help but think the pricing makes the larger, less tiered options more attractive. The options from the competing  phone nerds cost more per GB but offer the ability to have a lower monthly cost.

For comparison, standard 3.5”/7200RPM hard drives are about $0.045/GB for a 1TB drive at the local tech store. My file server costs probably about 45¢ a month on my electric bill, since it’s a low power N-series processor instead of an actually worth using CPU.
