If you are writing a ton of small files (we have billions of audit blobs we write) the API put costs can quickly creep up on your. We pay much more for those than on the actual storage costs. If you want to use tags on your objects, they charge you per tag per object per month - again, another huge cost. We missed that when pricing S3 out, and needed to do a project to pull out all of the tags we had, and are currently working on batching up multiple blobs into one larger blobs to hopefully reduce our API costs by an order of magnitude. This is purely a cost decision for us, adding complexity to our application and its operation. S3 seems better suited for fewer larger files. Our backups and other use cases like that work perfectly.
