Amazon EFS Pricing: The Throughput Mode and Storage Class Decisions That Decide the Bill
EFS Standard is $0.30/GB-month — over 13× S3 Standard. Standard-IA is 92% cheaper at $0.025; Archive is 99% cheaper at $0.0036. Elastic Throughput (the 2024 default) bills $0.03/GB read and $0.06/GB write per transfer. Throughput mode and storage class decisions, made once at provision time, control the bill more than any usage pattern.
