Thanks. I remember your earlier article where you wrote Third, if you have an item with only one attribute, and your read:write ratio is more than 22:1, it's cheaper to use S3 instead of SimpleDB -- even ignoring the storage cost -- since S3's 1 μ$ per GET is cheaper than SimpleDB's 1.305 μ$ per GetAttributes request. and wondered if that still held true for varying I/O rates.
