Speed. Speed. Speed.

Wasabi's system architecture enables a faster performance relative to Amazon S3*. This performance advantage also translates to significantly faster time-to-first-byte speeds when compared to Amazon S3.

100% Bit Compatible Amazon S3 API

Wasabi is built to be 100% AWS S3 bit-compatible (same AWS API constructs for storage & identity management). No need to change your S3-compatible application when using Wasabi.


Wasabi’s system architecture and design provides average time-to-first-byte (TTFB) performance that is less than 15 ms. This is significantly less than TTFB performance typically reported for Amazon S3.

Internal Consistency

Internal consistency means that when you write an object to a Wasabi storage bucket, it can be read immediately after writing.


Protecting your data against accidents, hackers, snoops, sabotage, and buggy applications

Wasabi protects your data in two ways: First, our unique immutable buckets protect your data against accidental or malicious destruction. Second, our strong encryption protects your data against hackers and snoops who want to steal your data

Why Wasabi
Durability and Protection

Wasabi’s durability is 11 x 9s, the same as Amazon S3. To put that in context, if you have 10,000,000 objects stored with Wasabi, then 11 x 9s of durability translates into 1 lost file every 10,000 years. That’s why most data loss nowadays is due to human error, application software bugs, or malicious destruction.


When you create a storage bucket in Wasabi, you have the option of making that bucket “immutable.” That means that data written to that bucket cannot be erased or altered. This allows applications built on Wasabi to be HIPAA, FINRA, and CJIS compliant. But it also protects your data from accidental deletions, application software bugs, hackers, malware, viruses, malicious destruction or alteration of data by employees or consultants, etc.

Active Integrity Checking

When using cloud storage for long-term file duration, how do you really know if the integrity of the file is intact? With Wasabi, you don’t have to worry about this because all stored objects are read and checked for integrity every 90 days for the duration the object is stored.


Below is a short list of frequently asked questions about Object Storage for Amazon S3.
1. What is Wasabi?

Wasabi is a cloud-based object storage service for a broad range of applications and use cases. Wasabi is designed for individuals and organizations that require a high-performance, reliable, and secure data storage infrastructure at minimal cost.

2. What is the difference between Amazon S3 and Wasabi?

Wasabi is designed to be 100% bit compatible with Amazon S3. This means any storage application that uses Amazon 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 80% less than Amazon S3 for storage and has a much simpler pricing model. The only charges from Wasabi are storage (there are no additional charges for HTTP PUTs, GETs, DELETEs, etc. and with the Wasabi Unlimited Free Egress pricing plan, there is no charge for egress)
  • 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 Amazon 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 Amazon S3 approach.

3. Can I store my data in Wasabi but run my application in Amazon’s cloud?

Yes. Wasabi uses Amazon’s Direct Connect capabilities to allow high speed transfer of data to and from Wasabi from Amazon’s other cloud services, such as EC2.

4. Can I use Wasabi to store the primary or secondary copy of my data?

Yes, Wasabi can be used to store primary or secondary copies of your data. Given the significant price and performance advantages that Wasabi provides over Amazon S3, there are advantages to using Wasabi for all data sets. However, Wasabi recognizes that given the incumbent nature of Amazon S3, some organizations may wish to continuing using Amazon S3 for their primary data set storage. In this scenario, Wasabi provides an inexpensive and highly durable storage repository for a secondary copy of your data.

5. What can I do with Wasabi?

Wasabi provides a simple web service interface that is 100% Amazon S3 bit compatible that can be used to store and retrieve any amount of data, at any time, from anywhere on the web. Using Wasabi, developers can easily build applications that make use of cloud-based storage. Because Wasabi is highly scalable and you only pay for what you use, developers can start small and grow their application as they wish, with no compromise on performance or reliability.

6. How can I start using Wasabi?

To start using Wasabi, click the “Try It Free” button on the Wasabi web page. After setting up an account, please refer to the documentation on the Wasabi Help page to begin using Wasabi.

7. What kind of data can I store?

Wasabi allows you to store virtually any kind of data in any format. Please refer to the Wasabi Terms of Use Agreement for details.

8. How much data can I store?

The total volume of data and number of objects you can store with Wasabi is unlimited (note that the free trial is capped at 1 TB). Individual objects stored in Wasabi can range in size from a minimum of zero bytes to a maximum of 5 terabytes. The largest object that can be uploaded in a single HTTP PUT is 5 gigabytes. For objects larger than 100 megabytes, Wasabi recommends customers consider using the multi-part upload capability.

9. What storage classes does Wasabi offer?

Wasabi currently offers a single class of object storage. Wasabi recognizes that Amazon offers several different object storage classes (S3, S3 Infrequent Access, and Glacier) to meet various customer performance and price requirements. However, at Wasabi, this range of service classes is not necessary due to the fact that Wasabi can provide better than Amazon S3 performance at lower than Amazon Glacier prices.

10. What does Wasabi do with my data stored in the Wasabi cloud?

Wasabi will store your data and track its associated usage for billing purposes. Wasabi will not otherwise access your data for any purpose outside of the Wasabi offering, except when required to do so by law. Please refer to the Wasabi Terms of Service Agreement for details.

11. How do I interface with Wasabi?

Wasabi provides a simple, standards-based REST web services interface that is designed to work with any Internet-development toolkit. The operations are intentionally made simple to make it easy to add new distribution protocols and functional layers. This interface is also 100% bit-compatible with Amazon S3. This means any storage application that works with Amazon S3 will work with Wasabi (with no changes required to the storage application code).

12. How reliable is Wasabi?

The Wasabi infrastructure has been built using industry best practices for redundancy in data center design.

13. What data consistency model does Wasabi employ?

Wasabi storage buckets provide read-after-write consistency for HTTP PUTs of new objects and eventual consistency for overwrite HTTP PUTs and HTTP DELETEs. Wasabi also uses a data consistency model that means any operation followed by another operation will always give the same results. This Wasabi data consistency approach is in contrast to the Amazon S3 model which is “eventually consistent” in that you may get different results in two requests.

14. What happens if traffic from my application suddenly spikes?

Wasabi is engineered to handle Internet application traffic, regardless of spikes. The Wasabi consumption-based pricing model and unlimited capacity ensures that your incremental costs don’t change and that your service is not interrupted in the event of a spike in traffic.

15. How secure is my data?

Wasabi is secure by default and all data stored in the Wasabi cloud is always encrypted at rest (even if the requesting party doesn’t specify encryption).   Wasabi follows industry-best security models and security design practices. Examples of Wasabi security features include:

  • Buckets are only accessible to the bucket and object creators
  • Wasabi supports user authentication to control access to data.
  • Access control mechanisms such as bucket policies and Access Control Lists (ACLs) can be used to selectively grant permissions to users and groups of users
  • HTTPS is supported for the secure upload/download of data

More info on Wasabi and security can be found here.

16. Does Wasabi support data access auditing?

Yes, customers can optionally configure Wasabi buckets to create access log records for all requests made against it. These access log records can be used for audit purposes and contain details about the request, such as the request type, the resources specified in the request, and the time and date the request was processed.

17. How durable is Wasabi?

Wasabi is designed to provide eleven nines (99.999999999%) durability of objects over a given year. This durability level corresponds to an average annual expected loss of 0.000000001% of objects. For example, if you store 10,000 objects with Wasabi, you can on average expect to incur a loss of a single object once every 10,000,000 years.

As with any environments, the best practice is to have a backup and to put in place safeguards against malicious or accidental user errors. This best practice approach includes secure access permissions, versioning and a functioning, regularly tested backup. In addition, Wasabi provides durability and compliance at the storage bucket level to prohibit deletion of the data in a bucket.

18. Does Wasabi support versioning?

Yes. The versioning feature with a cloud storage service offers an additional level of protection by providing a means of recovery when customers accidentally overwrite or delete objects. This allows you to easily recover from unintended user actions and application failures. You can also use versioning for data retention and archiving.

The Wasabi versioning feature allows you to preserve, retrieve, and restore every version of every object stored in a Wasabi bucket. Once you enable versioning for a bucket, Wasabi preserves existing objects anytime you perform a PUT, POST, COPY, or DELETE operation on them. By default, GET requests will retrieve the most recently written version. Older versions of an overwritten or deleted object can be retrieved by specifying a version in the request.

19. Where is my data stored and how are Wasabi's data centers secured?

Wasabi is deployed in fully secure and redundant data centers that are certified for SOC-2, ISO 27001, and PCI-DSS.   Our primary production data center is in the us-east region and additional data centers in other regions will be activated soon.   Please contact us if you have specific questions in this area.
