Storage Classes
Storage classes
As a user you have the ability to chose a storage class for your table. There are 2 storage classes - the difference between the 2 is in the storage cost & read write cost but they deliver the same performance.
Key difference is that I/O cost for Standard-IA is higher compared to Standard.
Storage cost for Standard-IA is cheaper compared to Standard
If your table is large in size with low Reads/Writes you will save by using the storage class Standard-IA. Example of such workload is a stream capture of device data with real-time anomaly detection.
