What is the total amount of storage offered by Amazon S3?

Amazon S3 is designed for massive scale and provides virtually unlimited storage capacity. While individual S3 objects have a size limit of 5 terabytes (TB), the total volume of data and the number of objects that can be stored in an S3 account are unlimited. AWS manages the underlying infrastructure to scale seamlessly as a customer's storage needs grow, eliminating the need for users to provision storage capacity in advance.

A. WOMB: This is not a unit of storage capacity. It may be a distractor referring to the "Write Once, Read Many" (WORM) model, which is a feature of S3 Object Lock, not a storage limit.

B. 5 GB: This is the maximum size for an object that can be uploaded to S3 in a single PUT operation. It is not the total storage limit for the service.

C. 5 TB: This is the maximum size for a single object that can be stored in Amazon S3. It is an object-level limit, not the total storage capacity offered by the service.

such as the number of buckets per account. Notably

it does not list any quota for the total storage amount

reinforcing its unlimited nature. It does

however

specify the "Maximum object size" as 5 TB.
