Wasabi is designed to be 100% bit compatible with Amazon Web Services (AWS) S3. This means any storage application that uses AWS S3 can also use Wasabi without any code changes to the storage application.
Both Wasabi and Amazon S3 offer high durability: eleven 9s (99.999999999%). However, there are several important price and performance differences:
- Price: Wasabi charges roughly 1/5th the price of AWS S3 for storage and has a much simpler pricing model. The only charges from Wasabi are storage (there are no additional charges for egress or API requests).
- Performance: Wasabi has much higher sustained read and write speeds . In addition, with Wasabi, the time to first byte is a fraction of the time when compared with AWS S3.
- Immutability: A Wasabi bucket can be made immutable by simply checking a box at the time of creation. This protects data from accidental or malicious deletion or overwriting, bugs in application software, hackers, etc. It is an important component in HIPAA, CJIS, FINRA, and other regulatory requirements. This simple Wasabi approach to immutability is in contrast to a more complicated AWS S3 approach.
