You can just use RDS m1.smalls then. We have databases that are 20-40GB running off smalls with relatively high throughput (more than I expected when builiding it for sure). $200/mo minimum pricetag is extremely high for 300mb of data, or even 10GB of data. We're looking at migrating a product of ours to Aurora and it has an operational dataset on the order of terabytes. (inb4 nosql: Why not NoSQL? It needs transactions that don't suck (I'm looking at you Cassandra). We use C* for other large datasets, I do wish we could just use that.)
