- Our 1TB plan costs only 3x the 100GB plan. This model works under the assumption that the average utilization of a 1TB plan (across all customers) will be ~30%.
- If we were to bring in an intermediary plan (say 500GB), we would have to increase the pricing of the 1TB plan (since at least 50% will now be utilized), and also set the price of the 500GB plan to at least 2x of the 100GB plan. Both plans now appear unattractive.
- Since Apple and Google don't support per GB billing yet (which IMO would have been the fairest way to go), we had to pick buckets, and the current ones seemed like the fairest possible.
I hope this makes sense.
