It would probably be helpful if you broke up the read/writes estimates. Also, are those writes mostly inserts or updates? There are different types of solutions depending one what you expect your profile to be like. Also are you reads just a key look up or are you doing some sort of aggregation/searching across all records? Please also estimate your overall size demands. Manipulating 2GB of data is different than 200GB. :)
