> “Of course the AWS S3 Express storage costs are still 8x higher than S3 standard, but that’s a non issue for any modern data storage system. Data can be trivially landed into low latency S3 Express buckets, and then compacted out to S3 Standard buckets asynchronously. Most modern data systems already have a form of compaction anyways, so this “storage tiering” is effectively free.”

This is key insight. The data storage cost essentially becomes negligible and latency goes down by a magnitude by making S3 Express as a buffer storage then moving data to standard S3. I see a future where most data-intensive apps would use S3 as main storage layer.

Did you conveniently ignore egress costs?

sounds a bit like CPU caches and main memory

Or like SSD’s vs spinning disks…
