This process is more of a thought experiment. We will present some very rough estimates of IO performance for many different disk types. For each, we should increment entries in our hardware spreadsheet based on perceived need.
The main things we will need for this process are numbers. During development, applications commonly have a goal, expected client count, table count, estimated growth rates, and so on. Even if we have to guess for many of these, they will all contribute to our IOPS requirements. Have these numbers ready, even if they're simply guesses.
If the application already exists on a development or stage environment, try to get the development or QA team to run operational tests. This is a great opportunity to ...
