A technology blogger wants to write a review on the comparative pricing for various storage types available on AWS Cloud. The blogger has created a test file of size 1 gigabytes with some random data. Next he copies this test file into AWS S3 Standard storage class, provisions an Amazon EBS volume (General Purpose SSD (gp2)) with 100 gigabytes of provisioned storage and copies the test file into the Amazon EBS volume, and lastly copies the test file into an Amazon EFS Standard Storage filesystem. At the end of the month, he analyses the bill for costs incurred on the respective storage types for the test file. What is the correct order of the storage charges incurred for the test file on these three storage types?
