To be clear, the auto-scaling with provisioned capacity still lags behind demand quite a bit. The new on-demand pricing makes this a non-issue but you pay for it at much higher cost at any sort of sustained load. https://serverless.com/blog/dynamodb-on-demand-serverless/ https://serverless.com/blog/dynamodb-on-demand-serverless/ has a good breakdown of when to use on-demand vs provisioned capacity.

The faster the disks the less time it takes. Now, writes can "fail" so you need to wait/retry or put it back on a queue to reprocess when you have write units available (both of those and the associated logging will cost you $ on AWS).
